Much slower IPS performance in 9.1x

Hi,

I just up2date'd from 9.006 to 9.105, and I'm seeing much lower throughput.

Previously, I was getting 65mbps from LAN->DMZ, and was easily able to max out my FiOS Internet connection (25mbps down).

Those tests were on 7.509, but I was still easily maxing out my 25mbps connection on 9.0x.

However, after the up2date to 9.105, I am now only getting 16mbps. 'top' and 'htop' show a snort thread using 97% of the CPU.

The CPU is an Atom n270 (single core + HT).
RAM is 2GB;

Hi,

At the moment, I'm copying a large mkv file from my LAN to a DMZ with Windows SMB/CIFS, and am only getting 4-5mbps.
I get 30mbps+ on the same LAN with the same hard drives.

If I stop the IPS, it jumps to 17mbps.

Note this is with Intel NICs and the Atom n270 CPU, and I'm on 9.016-017 now.
