Hi,
Yes, I am developer in GlassFish team. My experience with Apache is
mainly to make it work with GlassFish load-balancer plugin.
I have not experimented on number of concurrent users. I don't think
load-balancer plugin will impact that in any case. Do you see number of
concurrent users being less when you install load-balancer plugin? Which
OS are you using? Are ports 1024-65536 enabled to be used on your system
?(Only on windows, it requires additional settings.)
I have made few throughput runs recently. I found throughput achieved
using GlassFish load-balancer plugin is almost same as you will get
using mod_proxy or mod_jk on Apache.
Thanks,
Kshitiz
