Subject Re: Are response times skewed by GC pauses ?

Surely GCs affects response times shown by JMeter.
You should always monitor the GC behavior on your JMeter JVM (GC logs) and
if you see too much of CPU spent on GC you may need to increase the XMS XMX
JVM params. You may also want to remove objects from your test plan which
are known for using too much of CPU or Memory during load tests described


Shmuel Krakower. - re-use your jmeter scripts for application performance
monitoring from worldwide locations for free.
