Hi all,

I have a quick question regarding the estimated load of Tomcat 4.0 - running 
behind Apache 1.3.22, using the WARP connector, and both on the same machine 
(Linux).

I have read alot about the inability of mod_webapp to do serious load 
balancing - I've gathered that production-style scalability can only be 
achieved through the use of the mod_jk connector.

However, I can't seem to find any explicit estimations of the kind of load 
to be expected when using the above setup - in terms of concurrent servlet 
requests by muliple clients/machines.  How many concurrent connections are 
we talking about here?  Or more specifically, where does the line fall 
between "production use" and "normal use".  I know this is probably a 
personal/context-related issue, but I was interested in just how much you 
can bash Tomcat 4.0 before hassles arise.

My question is sparked by problems in our own setup, whereby concurrent 
requests for the same servlet result in an internal error (NullPointer 
exception, that was previously not a problem) - after only about 10-15 
consecutive requests each.  I'm still trying to track down any possibilities 
of client/server code errors.

Any thoughts/comments would be greatly appreciated.

Thanks,
Lucy
