We ran into a similar situation quite a while ago when we are at 5000 or
so users. We could run 5000 users on one system, but when we moved to
multiple webservers the throughput dropped.
At that time we were using nfsv4 to access the filestore and it turned
out that there were performance issues with it. We now use nfsv3 (both
on the client and server) and that problem disappeared.
Which version of nfs are you using ?

Hi, Guys
It bothered me a quite long time. Olio/PHP could pass 15000 concurrent
users with 2 webservers without any errors. However when I added one
more web servers, Olio failed with 15000u. The most errors were
"doTagSearch read time out", then throughput droped. I tested Olio
with any 2 webservers of the 3 webservers, all can pass 15000u. But if
3 webservers were togehter used, it will fail.
Any suggestions are appreciated. It really bothered my a lot. :-(
Thx, Xuekun
