Hi David, thanks for the review !
I wonder how useful this OPT_SPEED_SRC list is these days ; from what I heard it was setup a long time ago and also some tests/benchmarks were done back then. But in the meantime probably a lot of new files were added to the hs codebase that are also performance sensitive.
On the other hand , the compilers were switched a few times between introduction of the OPT_SPEED_SRC  list and now, so  who knows how valid the list is even for the files in it currently.
