Hi,

My target would be to have 20req/sec, I just don't get what's wrong there :
at the very start it's very fast then it's getting very slow...? and I can't
have more than 6.3req/sec

Apr  2 17:05:46 search-06 jsvc.exec[6423]: 358.744: [ParNew

0.0119440 secs] 3603202K->3535363K(4185792K), 0.0120160 secs] [Times:

This is my conf: (ive 8G ram) my index is just 11G

JAVA_OPTS="-Xmx4500M -Xms4G
                   -XX:+UseConcMarkSweepGC \
                   -XX:+CMSClassUnloadingEnabled \
                   -XX:-CMSParallelRemarkEnabled \
                   -XX:+UseCMSCompactAtFullCollection \
                   -XX:+UseParNewGC \
                   -Xloggc:\data\gc.log -XX:+PrintGCDetails -verbose:gc"


Any suggestion would be excellent,
Thanks
