Note that valgrind can also do cache modelling so I suspect it can give you a reasonably good picture of execution; certainly better than runtime. However, the trade-off is that (last I checked) it's incredibly slow. Don't you think I mean just a bit less peppy than usual. I mean soul-crushingly, mollasses-on-a-cold-December-morning slow.
If we think that we can bear the cost of running valigrind then I think it would be a great improvement. As you point out, the current run times are essentially useless.
I did it for my thesis and I found it ok. I mean I always sent it off to some machine and looked at the results later, so I did not really care whether it took 30mins or 2h. I think I’ll try it in perf.haskell.org and see what happens. Joachim -- Joachim “nomeata” Breitner mail@joachim-breitner.de https://www.joachim-breitner.de/
