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;

I'm not really into this, but it shouldn't really differ how many users you have. With a Celeron probably your CPU is the limiting factor that cannot handle multiple instances very well and probably is faster with only 1 instance.
