This might be obvious, but if you can, you generally want to run APA on the
slowest system you own, because modern machines are too bloody fast: it can
have trouble identifying hotspots because it only goes to (I think) 100K
samples per second, and that's not enough. At least, that's what ISTR from
using it a few years ago-on then-current machines. Unless APA has increased
that granularity, this problem can only have gotten worse.

 

I've heard of people considering a zPDT just so they could have a SLOWER
system to test on-when was the last time you heard that?
