Re: [Snort-users] Backend DB's

I was wondering what people are using for backend databases. Currently
I use MySQL 5, using myisam for the db engine. We are looking at moving
to InodeDB for the db engine. Our DBA is saying that we may get some
performance improvements. I want to get some more info as to what
people are using and if anyone has any info on the myisam vs inodedb
system.

We're using MySQL with isam.  Database performance is a non-issue with
regard to the sensors since we're using barnyard.  We typically see
aggregate per-minute alert rates in the double digits, with occasional
spikes into triple digits.

So I guess my bottom line to anyone looking for performance gains around
their sensors is to; 1) use barnyard and 2) tune your rule set.  If database
performance is still an issue after that, then you've got a lot of sensors
and should maybe have more than one database.
