Re[2]: huge performance hit when separating apache and jserv

[ba...@mssm.edu]

Gunnar,

I don't know much about LocalDirector, so this may be a stupid question, 
but anyway: If you used sessions, how did you bind a Session to a 
particular server?   You couldn't have by using JServ without hitting 
the same performance problem, as jserv would still need to re-route 
session bound requests to the appropriate app servers.  

Regards, 
Barnabas

I've seen it, but I didn't have the time to solve the problem. We just did 
load balancing on web server level using Cisco LocalDirector instead.

It's not a stupid question. The reason we went with this solution was that
the servlet application in question did not make use of sessions. 
But if you need sessions I would suggest you start profiling/debugging
mod_jserv and JServ to find the culprit. Use the source :-)
