Yes, the default was 5, and I do have verbose trace turned on.

But from the trace file I compare (50 and 100), I cannot see clear
difference. Maybe I was wrong.

Thx & rgds,

Try the command

snmpCollect ?

which will tell you what the default value of NumberConcurrentSnmp is.

Unless this was a new installation of NetView, your "original" value may 
not be the default.

The statement that you can increase it if you have network capacity and 
NetView system capacity makes sense to me.

My guess is that to increase the number of concurrent requests snmpCollect 
is going to have to maintain more state information or fork off new 
processes. In each case this will need more CPU and memory and the question 
is where does it start hitting limits on your box.

You should be able to see what happens by monitoring the trace file as you 
increase the number.

I suggested the -S switch in my previous email. Did that give you 
configuration information that shed some light?

Do you have verbose tracing on?  (-V and -T switches.)
