Hi, Am I doing something wrong, or did profiling performance drop an order of magnitude with GHC 6.2? When I compile my program with '-prof -auto-all', it takes about ten times as long to run as it does without. I use -O2 in both cases, and run without any run-time profiling options switched on. (The reported time, OTOH, seems about right) I though that previously profiling-compiling programs would only have marginal effects, and only running with heap profiling on would really slow things down. If this is a recent 'feature' and not just my brain getting its wires crossed again, is there any way to alleviate this (downgrade to x.y, build CVS HEAD, whatever)? (GHC 6.2 on Linux, tested with RPM package and Gentoo binary distribution) -kzm -- If I haven't seen further, it is by standing in the footprints of giants
