There are certainly optimizations... I would, however, be curious about how much memory that your system has and how much is being used... Could be a simple sizing issue... and 17K rules is a ton of rules!
Definitely isn't due to a lack of RAM: Mem: 74172428k total, 44161812k used, 30010616k free, 503960k buffers Or: Mem: 8174188k total, 3894432k used, 4279756k free, 517068k buffers Swap: 4194288k total, 0k used, 4194288k free, 842948k cached It isn't paging/swapping when it is doing this, processor is totally pegged though. And IIRC, if it was disk swapping/waiting stuff, that would show up as system in the time command output: real 4m54.605s user 4m52.632s sys 0m0.915s Since all the time is user, then it should be the Snort process its self needing this amount of processing power to load up the rules. 17k is a ton of rules, but the engine runs with all that loaded up pretty darn good (plus other rulesets on top of these even). It is just the startup time that takes forever. -- Eoin ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users Please visit http://blog.snort.org to stay current on all the latest Snort news!
