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 in: http://www.ubik-ingenierie.com/ubikwiki/index.php?title=JMeter_Performance_and_Tuning_Tips
Best, Shmuel Krakower. www.Beatsoo.org - re-use your jmeter scripts for application performance monitoring from worldwide locations for free.
