k. got it. Here's the situation:
My performance test goes like that:
- reading a file into memory (employees data)
. PTC (perfomance test center) creates posts (HTTP) to a servlet (JBoss client)
- This servlet makes an lookup to a stateless session bean --> business
method createEmployee() for this Person
- The Session bean does lookup personHome, addressHome & companyHome (homes
of entity beans)
- create-method on all entity beans (spread person's data to three tables)
-->CMP to a postgres db
- Servlet reads fully back the http-answer which is a formular again
- new data post happens
- so actually all data of a person (from PTC to servlet to jboss to db) is
going to be persistent in a frequency of ~450ms
The Memory increase from post to post (linear). When I stop the test and
jboss is still running, the allocated memory stays. After ~350 persistent
entries the use of memory has increased around 150MBytes! Wrapper
passivating beans doesn't free any memory.
I hope you get an idea and maybe tell me what I'm doing wrong...
Thanx, Mike.
