Re: NETTYPE's poll thread number
Version of IDS from 9, number of max connection is number of poll threads multipy by user per thread
e.g NETTYPE soctcp, 2,100, NET : Max connection is 2x100 = 200
So first you have to monitor number of user connections before fill the number in
by command : onstat -u , onstat -g ses , onstat -g ntu
--> NETTYPE soctcp, 2,100, NET
Meaning of the columns are (v9 +)
soctcp : OS net protocol
2 : 2 poll threads
100 : 100 user per poll thread
NET : Using net vp to run the poll thread
if you use CPU , IDS will use cpu vp to run poll thread so the number will has been forced by
number of physical CPU
If you allocate more poll threads will effect the overall performance.
but allocate less poll threads will make IDS accecpt connection slowly.

Operating System?
Version of the Engine?
NETTYPE soctcp,4,2000,NET (This is on a NET VP not a CPU VP)

Is ids version 7.31 will make any difference ?

There is a bug which means that ... the second figure (i.e. the 100
above) is a better number to use for the total number of connections
until 9.40.xC9.
If you look at the output from onstat -g ntt, you see the "100", which
does not change even if you increase the poll threads.
Check it out :D
