ausearch checkpoint question

[LC Bruzenak]

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
