I recently upgraded to ZCS 6.0.2 from 5.0.18... I remember ZCS 5 using about 15% of the CPU when idle. ZCS 6 uses about 25%...

Is this normal? and is there any thing I can do to trim that down a little? As it is I've turned off Anti-virus, spam and the logger to see if I could narrow usage down a bit and that doesn't seem to have made any difference. According to top the java server process seems to explode to 100% cpu, every 4 or 5 seconds.
