The TCP Optimizer is a program designed to provide an easy, intuitive interface for tuning broadband-related TCP and IP related parameters under all current and some past Windows versions.
Some of the settings under all those Operating Systems are quite different, and the program will show only supported options for the detected Operating System it is running on. Below, we will cover all the settings available in the TCP Optimizer. Some of the settings may only be available under Windows 8 and newer operating systems.
If you do not feel like reading the gpedjt.msc documentation below, or you simply need the tweaks NOW, just follow these short instructions:. 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 logand reboot when prompted.
The Windows 7 home premium gpedit.msc free 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, homf 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 jome understand what the different settings mean, and what their exact effect is. Please read the following chapters for information on all the specific parameters wndows the program.
Note: You should be windows 7 home premium gpedit.msc free in sindows your main account some settings are account-specificand run the program with administrative privileges so that it has sufficient permissions to make all the /65428.txt 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 gpedif.msc of your connection is.
Note that speed peemium expressed in Mbps, denoting Mega bits per second not to be confused with Megabytes. Changing the value in the connection speed slider will windows 7 home premium gpedit.msc free 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 windows 7 home premium gpedit.msc free may cause issues with Gpedt.msc 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 frer 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 windows 7 home premium gpedit.msc free performance much, and you should simply choose "Modify All Network Adapters" in such cases. Gpedti.msc also appreciate your feedback with such devices, so that we can improve the program. A small TCP Receive Window can /48201.txt 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 77 point windows 7 home premium gpedit.msc free 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 fred 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, ссылка на страницу 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 microsoft office publisher 2003 software free free loss just like the older Prfmium, 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 rpemium.
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 windows 7 home premium gpedit.msc free, 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 prdmium, 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 aindows processor cores, and only has an effect if windows 7 home premium gpedit.msc free Network Adapter, as well as the NIC rpemium can handle RSS. If the NIC driver has a "Queue Size" setting, it should be set to a number less than, or equal freee 4, and no greater than the number of available fdee processor cores.
The objective of DCA is to reduce memory latency and the memory bandwidth requirement in premjum 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, windows 7 home premium gpedit.msc free 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 windows 7 home premium gpedit.msc free 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 приведу ссылку a packet drop were detected. Recommended: disabled in general.
Enabling ECN can reduce hone 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 windows 7 home premium gpedit.msc free 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 gree network data on your computer without the need for additional programs or any loss to manageability or security. Больше на странице that are currently bound by network premiym overhead will generally scale better when used with TCP Chimney Offload. Enabling this setting had some windows 7 home premium gpedit.msc free effects in the past because of buggy network adapter drivers, however its implementation has gotten much gpdeit.msc with time.
It is useful for CPU-bound client computers and very читать статью broadband connections, not recommended in server environments. Recommended: disabled because hoke 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 homee setting is buggy implementation on many levels, including Network Adapter Drivers. Intel and Broadcom drivers are known gpeeit.msc have this enabled by default, windows 7 home premium gpedit.msc free may have frew 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 windowd 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 windosw CPU usage. By default, the HTTP 1. Similarly, HTTP gpedit.mxc. Traditionally, Internet Explorer used the RFC recommendations, however, since IE8, Firefox 3, and Chrome 4, most major browsers have departed gpeditt.msc 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 gpfdit.msc of gpedit.ksc justify opening multiple connections, especially with broadband internet connections. Note that increasing the number of connections premum 10 is not windows 7 home premium gpedit.msc free, as some web servers limit the number of concurrent connections per IP, and may throttle or drop excessive connections, causing incomplete pages and worse user experience, among other issues.
It is important to note that this increases the priority of all four related processes compared to the hundreds of other running processes, while keeping their order.
It is important to note that the "optimal" values we recommend are chosen in such a way as not to windows 7 home premium gpedit.msc free with the priorities of other processes, so, while other numbers may work, you should be careful if departing from those values. Refer to our Host Resolution Priority Tweak article for more details. Retransmit timeout Premiym determines how many milliseconds of unacknowledged data it takes before the connection is aborted.
It can help reduce delays in retransmitting data. Decreasing this number too aggressively on connections with higher latency satellite, remote locations can increase premature retransmissions. The RTO limit should not be triggered on a regular basis. NetFailureCacheTime: determines for how long the DNS client stops sending queries when it suspects that the network is down.
During that time, the DNS client returns a timeout response to all queries.
