FW: AW: tomcat in the production environment
Velocity scales just fine to 200 concurrent users.

Subject: AW: tomcat in the production environment
Hi Kandasamy.
we are using Tomcat 3.3 on our production site. Solaris 2.7 Sparc, 2
processors,
JDK 1.3.1_01 mod_jk ajp1.3 behind two Apache 1.3.19 with a HW loadbalancer
in front.
And still our single Tomcat 3.3 instance is not the bottleneck. Currently it
is our
Oracle machine :)
BTW. we make heavy use of Velocity as well.
We have currently up to 200 concurrent users and I must say, Tomcat is the
most
stable and reliable piece in our architecture.
We have some JVM crashes when the heap fills up and sometimes at startup
(when there are already
many customers trying to log in) But this is clearly the JVM - not Tomcat.
But it is true, you have to make test for your environment.
All the best,
Regards,
Hans
