What do you mean by "an entity bean" or "full sized"? The key metric that
you are probably interested in is the number of EJB instances concurrently
processing events that a particular machine can handle.
The number of bean instances that a single processor machine can host
depends on a lot of factors including concurrency, memory availability, bean
size, processing done by the bean, database interaction and performance,
....
The two relevant benchmarks to look at are ECPerf and SPEC's JBB2000.
Carefully analysing the public disclosure documents of the results from
these tests will give you some idea of the machine capacities that you need.
JBB can be found at: http://www.spec.org/osg/jbb2000/
ECPerf at: http://ecperf.theserverside.com/ecperf/

Hi,
Anyone knows if one CPU is enough to run a full scale J2EE application. Are
there any benchmarks that show how many concurrent actions a 64 processor
can handle. Anyone know from experience how many entity beans (homes and
objects) were the maximum amount for one CPU?
Any help would be highly appreciated,
Daniel
