I have a three server configuration with 1 Apache (httpd) and 2 Tomcat
(10 instances a piece) servers. The configuration is working but it is
a little complicated. I choose this configuration for performance. I
loaded the tomcat servers with lots of RAM and let the multiple instance
run as independant processes under linux. This would allow, I beleieve
for beter CPU usage. There were serveral other reasons for my original
choice of load balancing across multiple instances on multiple machines
which I won't go into unless asked. But, my question is this. Is it
needed? Can I get the same performance from single tomcat instances on
the two boxes (rely on threads instead of POSIX proccesses)? Wouldn't
running 1 JVM instead of 10 provide a better use of memory per machine?
The configuration would be easier, definatly... What are the thought of
the others in this group? Thanks...
