[jira] [Commented] (SYNAPSE-1065) GC Overhead limit exceeded error during running a performance test on simple Passthough Proxy

    [ https://issues.apache.org/jira/browse/SYNAPSE-1065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15778895#comment-15778895 ] 

Vanjikumaran Sivajothy commented on SYNAPSE-1065:
-------------------------------------------------

[~chanakaudaya] As of now the allocated memory by default in the synapse.sh is {code}  JAVA_HOME/bin/java -server -Xms128M -Xmx128M \ {code}

If you want to conduct a load test, You may have to fine tune it further.

Currently i am using 

{code}
 -d64 -server \
            -Xms2024m -Xmx2024m -XX:PermSize=256m -Xmn1g \
	        -XX:+UseConcMarkSweepGC \
                -XX:+UseParNewGC \
	        -XX:-UseGCOverheadLimit \
	        -XX:+CMSClassUnloadingEnabled \
	        -XX:+CMSParallelRemarkEnabled \
	        -XX:+OptimizeStringConcat \
	        -XX:+UnlockDiagnosticVMOptions \
	        -XX:+DisableExplicitGC \
	        -XX:+UnsyncloadClass \
            -XX:CMSInitiatingOccupancyFraction=60 \
            -XX:+UseCMSInitiatingOccupancyOnly"

> I have a simple Passthrough Proxy and a back end service which is written in netty and simply echo back the request message. When I run a performance test using Jmeter (with 100 concurrency), I am getting the following errors in the synapse log file and console.
