[syslog-ng]syslog-ng performance

[cami]

Hi All,

I'm currently using syslog-ng on 8 of mta/mailhost machines
which are logging via tcp to a central loghost/server..
Each machine generates over 1 gig of logs.. syslog-ng is
eating away at system resouces in a big way, up to 40% of
the cpu (local logging is disabled).. Is there any optimizations
that can be made to try and chop down on cpu usage?
Perhaps a higher sync() value? Its currently set to 0..

Regards,
Cami
