OS: Ubuntu server 10.04 LTS x64
Release 7.1.0_GA_3140.UBUNTU10_64 UBUNTU10_64 NETWORK edition.
I just installed a trial of ZCS 7.1 NE for testing on a VMware ESXi 4.1 host. We noticed the server running unusually higher than our two production machines both with 100+ active accounts. The new 7.1 server has 4x 3.33 GHz processors and 4 GB RAM allocated with no active users accounts yet. Seeing as there is no one using the server yet I find this a bit odd. If we restart Zimbra or the server it goes back down to an acceptable level for a while then kicks back up to what we're seeing below.
Does anyone have performance recommendations for this scenario?
