https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234949 --- Comment #13 from Mark Johnston <markj@FreeBSD.org> --- Created attachment 204641 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=204641&action=edit proposed patch It turns out that libelftc provides some ELF string table routines which are more efficient than what strip uses today. With all of my diffs combined I get: > time strip ghc-8.6.2/libraries/Cabal/Cabal/dist-install/build/libHSCabal-2.4.0.1.a real 0m6.817s user 0m6.428s sys 0m0.135s > time strip ghc-8.6.2/libraries/Cabal/Cabal/dist-install/build/libHSCabal-2.4.0.1_p.a real 0m8.674s user 0m8.185s sys 0m0.155s vs. GNU strip: > time /usr/local/bin/strip ghc-8.6.2/libraries/Cabal/Cabal/dist-install/build/libHSCabal-2.4.0.1.a real 0m2.671s user 0m2.334s sys 0m0.245s > time /usr/local/bin/strip ghc-8.6.2/libraries/Cabal/Cabal/dist-install/build/libHSCabal-2.4.0.1_p.a real 0m4.161s user 0m3.599s sys 0m0.351s So there's clearly still room for improvement. I did not test my changes extensively yet, but I attached a combined patch if anyone else is interested in testing them with ports builds. -- You are receiving this mail because: You are the assignee for the bug.help
