Hello Sorry for the uninformative subject, but I've got no less than 3 questions about profiling in ghc. Here we go 1) Can I profile my program if I don't have all the libraries it depends on compiled with profiling? ghc says it can't find profiling variants of this and that module in other packages, when I try ghc -prof. I managed to build all the dependencies with profiling, but that being a necessity doesn't look good to me. Maybe there's a way to avoid that? Moreover, as far as I could tell functions from those packages didn't appear in the call graph after +RTS -p profiling. 2) Can I exclude a function from profiling? That probably means not assigning a cost centre to it. Typical case, I think. Database connect function is rather heavyweight (regarding time) compared to the rest of the code, and it takes up to 98% of time. So the rest of the picture is less informative than it could be. 3) Isn't it possible to have -p profiling data of the interrupted (ctrl-c) program? Thanks a lot! -- Daniil Elovkov
