Hi Sebb / Matt ,
Am using JMeter for Load testing our Java application . I have some doubts
on using JMeter . Could you please help me to solve my doubts pls ?
My Tuning Parameters are as follows
set HEAP=-Xms512m -Xmx1024m
set NEW=-XX:NewSize=128m -XX:MaxNewSize=128m
set SURVIVOR=-XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=50%
set TENURING=-XX:MaxTenuringThreshold=2
set EVACUATION=-XX:MaxLiveObjectEvacuationRatio=20%
set RMIGC=-Dsun.rmi.dgc.client.gcInterval=600000
-Dsun.rmi.dgc.server.gcInterval=600000
set PERM=-XX:PermSize=128m -XX:MaxPermSize=128m
set DEBUG=-verbose:gc -XX:+PrintTenuringDistribution
I have defined the Heap size as 512 - 1024 & My RAM size is 512 MB . I have
run my Test Plan using JDBC Connection configuration for 3964 concurrent
users successfully . If I use more than 4000 Users , JMeter shows Out of
Memory error . Even if i tried running the test plan by changing the Heap
size as 256 - 1024 , 768 - 1536 & 512 - 512 , there is no improvement on my
concurrent users , still am getting Out of memory error message
I tried the same test plan in another system which has 1 GB RAM , But in
that system, Only 2000 concurrent users have successfully completed and I
got the same Out of Memory error .
Could anyone / you please reveal me what I have to do to get proper results
for more than 5000 Concurrent users ?
Thanking you in Advance .
Thanking you .
With warm regards.,
