::
:: Uncomment the following GC settings if you see spikes in your throughput due
to Garbage Collection.
::
:: set JVM_OPTS=%JVM_OPTS% -XX:+UseParNewGC -XX:+UseConcMarkSweepGC
-XX:+UseTLAB -XX:NewSize=128m -XX:MaxNewSize=128m
:: set JVM_OPTS=%JVM_OPTS% -XX:MaxTenuringThreshold=0 -XX:SurvivorRatio=1024
-XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=60

Some utilities (like Visor) are hanged up in continuous GCs when connected to
large clusters (above one hundred nodes). Even after using large heap (about 32
Gb).
I'd like to propose to remove this lines and modify default JVM_OPTS as follows

set JVM_OPTS=-Xms1g -Xmx8g -XX:+UseG1GC -server -XX:+AggressiveOpts
-XX:MaxPermSize=256m
