Performance Issue

Postby fritz » Mar 08 19 2:47 pm

We've use wingate for couple years, It runs well for past years, But, recently we got the performance issue,
I have already referred to the user's manual, and the following two articles


For some reason, we didn't use the cache/web activity/log at the beginning,
but we found when client up to 1000, our wingate starts to make a mistake,
and I check the WGOption.exe , I see "Max network buffers" is set to 512,
then I change the setting and reboot, but I see "Max network buffers" still 512,
then check the registry HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\QbikhkVistaAMD32\Parameters
the registry looks like
I can't see the registry about the MaxNetBuffers, so should I add this registry directly??

And another question, if I change the "Max Network Buffers" from 512 to 8192, is it possible to handle 16K session??

My Server Spec
IBM X3650 M4/(Intel Xeon E5-2620 v2)*2/32gRAM/2008 R2 64bit

Hi I've been change the MaxNetBuffers to 2048,
But the situation still the same, when the client connection > 3000,
lots of the error like "timeout" or "connection problem" started to appear,
Will there be any way to deal with it ??

how many cores do you have for the WinGate server? If it's a VM how many cores does that have?

3000 users is a lot of concurrent connections, which makes a lot of threads in WinGate. If there are not enough cores, this increases the time threads need to wait to process I/O. This is independent of CPU utilisation as well, so the system can be saturated even if the CPU is showing relatively low usage.
