Snort is consuming 99% CPU on a:

model name      : Pentium III (Coppermine)
stepping        : 10
cpu MHz         : 931.013
cache size      : 256 KB

MemTotal:      1157752 kB
MemFree:       1039896 kB

Version 1.8.1-RELEASE (Build 74)
compiled with mysql support.

Sniffing a 100mbit wire, no packets dropping.

I was running snort in the same place with a celeron and the CPU never
reached 99% (that was snort 1.8.0 (?) I think).  Same compile options.

Any ideas ?
