CPU load in idle mode Wingate 6.1.2

Hi,

what does wingate do if it has nothing to do?

I see here on a wingate server with only SMTP,POP3 & IMAP Services activated a permanent load of 3-4% even if nothing happens (nobody connected). ENS etc. is also deactivated.

What is wingate doing in such idle phases? 0-2% sometime would be OK but permanently >3% CPU load???

Wingate constantly updates lots of things - routing tables, interface tables, etc. Besides, there are quite a lot of network packets wondering around - each of them can trigger a message to the engine (like WINS packets, for one). Besides, Wingate runs a number of threads even when it is idle - scheduling threads, driver communication thread, etc - and even when the threads are idle, they are being scheduled and re-scheduled by the system.

One other thing we have found chews a bit of CPU is on slower machines running 2k3 server with a lot of dial up profiles.

Enumeration of dialups takes about 50x as much resource (IO) on 2k3 than it does on XP or 2k (don't know why). This can use a bit of CPU on slower machines (i.e. less than 1GHz)
