Memory Usage

[Simon Funnell <si...@gmail.com>]

Hi,

I am looking at running a small ecommerce site with about 40-80 users at a
time on a virtual private server with 4 cores and 1GB of memory, I am
planning on running apache james, mysql and tomcat on this instance. My
question is will 256MB maximum heap memory with say 50 threads be enough to
handle the load without any out of memory errors?

Thanks.

No idea.

I've seen apps with 6GB heap fail with OOME with only 5 concurrent users
and other apps serve 1000s of users with a few hundred MB.

It all depends on the app and we can't see you code. Load testing and
profiling are strongly recommended.
