Descargar tcp optimizer windows 7 2012

Choose your Network Adapter that connects you to the Internet or tick "Modify all network adapters" Pick "Optimal settings" from the radio-buttons near the bottom of the program Click on the "Apply changes" button, choose to create backup and log , and reboot when prompted.

The TCP Optimizer can do all the rest of the work for you and optimize your internet connection. A preview of all relevant changes is available before they are actually applied. The program can be used to easily apply custom values, and test with different settings, if you'd prefer. To do so, you may have to read the rest of the documentation and our tweaking articles to understand what the different settings mean, and what their exact effect is. Please read the following chapters for information on all the specific parameters in the program.

Note: You should be logged in with your main account some settings are account-specific , and run the program with administrative privileges so that it has sufficient permissions to make all the necessary changes. This slider is intended for choosing your maximum possible internet connection speed, as advertised by your Internet Service Provider ISP. You should not use your current speed, or any speed test results here, rather what the maximum theoretical speed of your connection is.

Note that speed is expressed in Mbps, denoting Mega bits per second not to be confused with Megabytes. Changing the value in the connection speed slider will have some effect on the optimal TCP Window value. Under older Windows variants, it directly calculates the RWIN value optimal for the connection speed.

Under newer Windows OSes, it may change the auto-tuning algorithm restricted for speeds under 1Mbps, normal for most broadband connections, experimental for speeds over 1 Gbps, to be used with caution currently. Note that the "experimental" TCP Window auto-tuning setting should be used with caution, as it may cause some stability issues. Reportedly it may cause issues with Outlook connecting to mail servers, accessing local network shares, and Crashplan backups in some Windows versions.

If a specific network adapter is selected using the pull-down menu, its IP address will be displayed in the lower-right portion of this section.

You can also choose to modify all network adapters at the same time, or none of their individual setting. This section allows you to set a custom MTU value. It is only necessary to edit the MTU value in such special cases. Note: In some rare cases, it is possible that your desired network device is not correctly identified by the Optimizer.

That does not affect the program performance much, and you should simply choose "Modify All Network Adapters" in such cases. We'd also appreciate your feedback with such devices, so that we can improve the program. A small TCP Receive Window can limit high-speed, high-latency transfers, such as most broadband internet connections. We recommend setting this to "normal" for most connections, and, make sure that you disable "Windows Scaling heuristics" below so that Windows does not automatically modify this parameter.

If your connection speed is less than 1 Megabit per second, you can set it to "highlyrestricted". If you are on dial-up connection, you can try setting this to "disabled" as your speed will not need buffers larger than 64KB. This should be tested further, however, as it may cause some stability issues. If you experience any issues with the "experimental" setting please dial it back to "normal" and share your experience on the forums or via email.

If this is left enabled, Windows can restrict the TCP Receive Window at any point in time it decides that the network conditions justify it. It is highly recommended to set this parameter to "disabled", so that user-set TCP auto tuning settings are retained over time.

With broadband connections, these algorithms do not increase the TCP Window fast enough to fully utilize the available bandwidth. CTCP attempts to maximize throughput by monitoring delay variations and packet loss. It can improve throughput on higher latency and broadband internet connections. CTCP uses estimates of queue delay as a measure of congestion, and allocates buffers accordingly.

Note that this setting may only work on Server Operating System variants. New Reno treats retransmission timeouts RTO and duplicate ACKs as packet loss just like the older Reno, Tahoe algorithms, however it performs a fast retransmit and skips the slow start and enters "fast recovery".

It is actual congestion-based, rather than delay-based algorithm. The algorithm has some issues with out-of-order packets by more than 3 packet sequence numbers. The algorithm does not rely on the receipt of ACKs to increase the TCP window size, it is only dependent on the last congestion event.

With traditional algorithms, connection flows with very low latency have advantage as they receive ACKs much faster, and their buffers congestion window grow faster. It should in theory provide a more stable connection when the network is fully utilized, at the expense of a bit larger buffers.

RSS enables parallelized processing of received packets on multiple processors, while avoiding packet reordering. It separates packets into "flows" and uses different processors for processing each flow.

This should be enabled if you have two or more physical processor cores, and only has an effect if the Network Adapter, as well as the NIC driver can handle RSS. If the NIC driver has a "Queue Size" setting, it should be set to a number less than, or equal to 4, and no greater than the number of available physical processor cores. The objective of DCA is to reduce memory latency and the memory bandwidth requirement in high bandwidth Gigabit environments.

The TTL determines the maximum amount of time in seconds and the number of hops that an IP packet may live in the network without reaching its destination. It is effectively a limit on the number of routers that an IP packet is allowed to pass through before being discarded.

It does not directly affect speed, however a value that's too small can cause packets to be unable to reach distant servers at all. A very large value, on the other hand might take too long to recognize lost packets.

It is aimed to decrease retransmissions. In essence, ECN assumes that the cause of any packet loss is router congestion. It allows routers experiencing congestion to mark packets and allow clients to automatically lower their transfer rate to prevent further packet loss. The receiver echoes the congestion indication to the sender, which must react as though a packet drop were detected.

Recommended: disabled in general. Enabling ECN can reduce latency in some games with ECN-capable routers, and improve throughput in the presence of packet loss.

ECN is also recommended if using CoDel algorithm to combat latency by dropping slowest packets on congested links. Setting allows the network adapter to compute the checksum when transmitting packets and verify the checksum when receiving packets to free up CPU, reduce PCI traffic.

This helps improve the processing of network data on your computer without the need for additional programs or any loss to manageability or security. Programs that are currently bound by network processing overhead will generally scale better when used with TCP Chimney Offload. Enabling this setting had some negative effects in the past because of buggy network adapter drivers, however its implementation has gotten much better with time. It is useful for CPU-bound client computers and very fast broadband connections, not recommended in server environments.

Recommended: disabled because of buggy implementations and issues with it, also now considered deprecated by Microsoft now. When enabled, the network adapter hardware is used to complete data segmentation, theoretically faster than operating system software.

Theoretically, this feature may improve transmission performance, and reduce CPU load. The problem with this setting is buggy implementation on many levels, including Network Adapter Drivers. Intel and Broadcom drivers are known to have this enabled by default, and may have many issues with it. Timestamps are a RFC option that is intended to increase transmission reliability by retransmitting segments that are not acknowledged within some retransmission timeout RTO interval.

The problem with timestamps is that they add 12 bytes to the byte TCP header of each packet, so turning them on causes considerable overhead. In essence, it provides the ability to more efficiently move network data by minimizing CPU usage. By default, the HTTP 1. Similarly, HTTP 1. Traditionally, Internet Explorer used the RFC recommendations, however, since IE8, Firefox 3, and Chrome 4, most major browsers have departed from the recommendations in search of faster web page loading speed by increasing the number of parallel connections to web servers for both HTTP 1.

We recommend pushing this further to concurrent connections per web server, because of the complexity of web pages and the number of elements justify opening multiple connections, especially with broadband internet connections. I remember when my tech geek uncle went through all the tech magazines and tech websites one time to look for something new and different, but what he.

I was informed by a screen prompt that my computer must be restarted for the change's to take effect. After doing so.. I started the program once again in 'administrator mode' , when the program opened, instead of the 'optimal' button being highlighted like I had selected, the 'normal' button was.

I'm confused as to why this happened.. By the way.. I also installed this software on my wifes laptop that runs windows 7 home premium bit, it seems like it now takes longer that it used to establish a wi-fi connection.

Thanks, David :rolleyes: Update: Added connection information Hello David, It is normal behavior for the program to start with the "current" radio button selected, rather than the "optimal" one, the "optimal" settings were already applied.

Best, Philip. Hi Philip, Happy New Year! Thanks for a reply.. As I remember, previously I had Panda Free anti-virus installed on it, and as I remember the wifi connection seemed to connect somewhat quicker. I currently have a Pace AC. I still feel as though there MUST be a setting that could be changed so as to speed up the wireless connection to the gateway. Of course the culprit might be microsoft and one of their updates that could have affected the connection speed. Thanks, David. David, You can try turning off the anti-virus to check that theory.

I find the Microsoft Essentials adequate in most cases. Updated the TCP Optimizer to version 4. I have a strange probolem. Using Windows Using TCP optimizer 4 as Admin. These are settings when I run it I am doing stq wrong? Thank you. I had originally applied the optimizer settings to the onboard card, no problem.

I now launch the program with the intention of applying the optimization of the new card but the program won't detect my new card. Do you have any ideas why it might not see the new card in the adapter list?

Is there anything I can do? How about if you type the following in command prompt: netsh int ip show interfaces What is the name listed in the netsh output and the Registry hive? Phillip; 1. How to add the Network Card in the registry? I don't know your exact setup, and which of the two active Ethernet adapters you are using, without looking at your registry it is hard to debug.

In my version 4. I strongly advise you not to do this! So, if you experience the widespread problem of not being able to access "Restore Previous Versions" no previous versions available-error - check your TCP Window Auto-Tuning setting.

This is dependent on the "speed" slider setting, if you bump it up all the way to the end it may suggest "experimental" auto-tuning. You are correct this should be used with caution, I wasn't aware of the shares issue - thanks for the info. Thanks Philip! I wasn't aware of the speed slider changing the auto-tuning.

Wasn't the maximum of the speed slider previously at 10 Mbps? I think that's why it was cranked all the way up The TCP Optimizer has been updated to version 4.

We've updated the optimal recommended TCP Auto tuning level to: "disabled" for connections under Kbps, "restricted" up to 1 Mbps, and "normal" over 1 Mbps. Ran TCP Optimizer on my laptop and my download speeds have shot up from 30mbps to 52mbps Glad it worked that well for you! Hi all, Is this still the latest version? I have ver 4. Good to see there are still people here.

Hi Ashdaw : Yes, 4. Thanks for the positive feedback, we try to keep it current as the OS evolves :. Is ctcp still the best option to chose or are the "newly" added ones better? I've read through the documentation but i don't think it was listen sorry if it missed it. I would like to think Microsoft have made this change for a good reason. I am just worried a bit about the MS implementation, and users have different builds with various support, that is why we haven't moved on to recommend it yet in the program's "optimal" settings yet.

By all means try it.
