Much slower IPS performance in 9.1x

BarryG
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, 

    You don't need to reboot.

    Normally, with the default setting of '0', one instance will run per CPU Core or Thread.

    If you don't have enough RAM, this can be problematic (500-800GB used per instance).

    With 8GB RAM, you probably don't need to worry about it.
