Scaleability of Snort
Posted by uber on April 13, 2005 05:51:26
Hello all
I'm in the midst of trying to help a customer who is deploying Snort to monitor an internet connection that will....ahem.....push a metric *load of traffic to and from the Internet. Suffice it to say their firewalls have special high performance nics to handle the load.
My question is:
1. Are there any rough "rule of thumbs" of how much thruput (in megs/sec) Snort can handle before it goes tits up. Just so you know I'm currently studying Snort optimization strategies...I'm just trying to find a rough performance ceiling here.
2. Since Snort is a stateful packet inspector, it must keep some kind of state table. Can the size of this state table be tweaked? Any caveats on this? Where can I look to grok the granular config details?
Thanks all!
