ausearch checkpoint question

I'm using the 2.4.5-3 audit rpm set and I tried using the ausearch "checkpoint" option a couple weeks ago. This was on a moderately busy system (judging by my own systems/experience) generating say 300-400MB of data/day. I tried the checkpoint option in a 5-minute cron job, and I noticed that in comparison to the "-ts recent" option, it took far longer to complete. The "recent" option result was less than a second, whereas the checkpoint version took ~20 seconds every 5 minutes. It's possible there were other factors at play; e.g. it was used on a mls-policy machine, and although I saw no AVCs, it's possible there were some access issues I didn't have time to investigate. On my intended application, I'll be on a standard targeted-policy machine so this won't be a potential factor. I need to test this again, as I'm considering using the ausearch checkpoint capability for some new requirements, I was wondering if perhaps there were any timing results done or if there are any tips and tricks to getting the most out of it. Also - the man page section describing this is a little confusing to me so if anyone has a script segment that would be very helpful. Thanks in advance, LCB -- LC Bruzenak magitekltd.com
