Performance questions

[Lucas de Carvalho Ferreira - BMS <lucas.ferreira () bms com br>]

Hello,

I am trying to monitor a high traffic 100Mbs switch port with snort on a 433
MHz Celeron machine running Red Hat 7.2 but snort is dropping about 10% of
the packets, even if the CPU load is at an average of 70% (seen with top).
Is there any configuration tips for snort or for the Linux kernel to get
better performance? Could it be an I/O performance problem? 

Thanks a lot,
