2009年6月6日 · The client versions of Windows are restricted in the number of half-open connections. The 10 limit for XP is well known, Vista has other limits depending on the version (e.g. Home Basic has a limit of 2, Ultimate has 25). You can Google "Patch for Event ID 4226" to alleviate these limits.
2008年7月8日 · Due to the enhanced security in Vista, it is a bit more complicated to increase the TCP concurrent half-open connections limit. It requires downloading a patched tcpip.sys, changing a registry parameter and disabling driver signing in x64 editions (potentially after every reboot).

To check the current status of the Vista TCP/IP tweakable parameters, in elevated command prompt type the following command: You will be presented with something like the following: The settings, as well as their default and recommended state are explained below. The two most important tweakable parameters are "Auto-Tuning Level" and "Congestion Co...
Windows Vista/7 has the ability to automatically change its own TCP Window auto-tuning behavior to a more conservative state regardless of any user settings. It is possible for Windows to override the autotuninlevel even after an user sets their custom TCP auto-tuning level. When that behavior occurs, it can have a very noticeable negative impact o...
To turn off the default RWIN auto tuning behavior, (in elevated command prompt) type: The default auto-tuning level is "normal", and the possible settings for the above command are: Our recommendation: normal (unless you're experiencing problems). If you're experiencing problems with your NAT router or SPI firewall, try the "restricted", "highlyres...
Add-On Congestion Control Provider The traditional slow-start and congestion avoidance algorithms in TCP help avoid network congestion by gradually increasing the TCP window at the beginning of transfers until the TCP Receive Window boundary is reached, or packet loss occurs. For broadband internet connections that combine high TCP Window with high...
ECN (Explicit Congestion Notification, RFC 3168) is a mechanism that provides routers with an alternate method of communicating network congestion. 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 au...
The receive-side scaling setting enables parallelized processing of received packets on multiple processors, while avoiding packet reordering. It avoids packet reordering y separating packets into "flows", and using a single processor for processing all the packets for a given flow. Packets are separated into flows by computing a hash value based o...
TCP chimney offload enables Windows to offload all TCP processing for a connection to a network adapter. Offloads are initiated on a per-connection basis. Compared to task offload, TCP chimney offload further reduces networking-related CPU overhead, enabling better overall system performance by freeing up CPU time for other tasks. To set TCP Chimne...
Windows 7 and 2008 Server (but not Vista) add NETDMA 2.0 Direct cache access support. Direct Cache Access (DCA) allows a capable I/O device, such as a network controller, to deliver data directly into a CPU cache. The objective of DCA is to reduce memory latency and the memory bandwidth requirement in high bandwidth (Gigabit) environments. DCA requ...
It is sometimes useful to view and set the MTU value for a specific network interface manually. To view a list of active network interfaces and their MTU values in Vista using netsh, open command prompt as administrator and execute the following command: You will be presented with a list of interfaces, and their respective MTU values as follows: To...
Many of the registry keys tuning TCP/IP parameters from previous Windows versions no longer work in Vista and Server 2008. Below is a list of the few we've confirmed to still work, as well as some new additions. Note that for changes to these settings to take effect the computer needs to be rebooted. As always, a registry backup is recommended if m...
