[syslog-ng] Simple Doubt

Hi all, I have a doubt about a process that i have. Maybe the solution is in the side of syslog-ng, i am searching. My process is: Log -> Perl Script -> Fifo -> Syslog-ng -------------- > Syslog-ng -> perl -> rrd The problem is when the application write to many lines in the fifo file (through the perl script), my syslog-ng (Standard Configuration) can't process all lines quickly, and the load of cpu rises a lot. Is there any parameters that i can use to optimize the reading? Someone have a similar solution? Thanks a lot. Att., Luiz
