Back to this issue again. :-( If there are more than 10 queries simultaneously, what could happen besides performance slows done? Occasionally, it has "netsnmp_call_handlers() called illegally" log message. I don't know if it is related or not?

There are some optimizations (5.2 and beyond... hmm.. might be 5.1 actually, I forget) that help walk (getnext actually) requests find the next spot to start on whenever possible. It's possible two walks would actually bypass the optimization, but knowing how it works it should work until you hit like 8-9 walks at once. However, remember that the agent only processes one request at a time so you would get some compounding as the 2 application timing and the agent timings interplayed. Ideally if the applications themselves required 0ms to achieve there end you would get only a doubling. But with two apps and their own overhead it will affect the results (though the app should be much faster than the agent). -- Wes Hardaker Sparta, Inc. ------------------------------------------------------- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.
