Is this the original CentOS kernel? Also, did you set any strange kernel parameters during startup? I think CentOS kernel out-of-the-box usually handles this just fine. /Peter Från: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Stephen Wilde

It's very strange though, that a machine like this gives so poor timing results. The first thing I would do is to upgrade to latest GIT HEAD.
