https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229326 Bug ID: 229326 Summary: [patch] Mk/bsd.gecko.mk remove forced -O3 optimization Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: ports-bugs@FreeBSD.org Reporter: kennethsalerno@yahoo.com Created attachment 194619 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D194619&action= =3Dedit patch to remove -O3 for SET+=3DOPTIMIZED_CFLAGS (MOZ_OPTIMIZE_FLAGS) Hi, are we sure we want to append -O3 forcibly to CFLAGS for www/firefox? I have found it is just making the application larger compared to the default= -O2 set in CFLAGS but not necessarily resulting in any better performance, at l= east I can't really tell. For my laptop with inadequate RAM, it seems to perform better compiled with -O2 actually, I think. built with -O3: > pkg info firefox | grep size Flat size : 123MiB > ls -lh /usr/local/lib/firefox/{firefox,libxul.so} -rwxr-xr-x 1 root wheel 166K Jun 15 09:38 /usr/local/lib/firefox/firefox -rwxr-xr-x 1 root wheel 67M Jun 15 09:38 /usr/local/lib/firefox/libxul= .so built with -O2: > pkg info firefox | grep size Flat size : 121MiB > ls -lh /usr/local/lib/firefox/{firefox,libxul.so} -rwxr-xr-x 1 root wheel 162K Jun 24 15:51 /usr/local/lib/firefox/firefox -rwxr-xr-x 1 root wheel 65M Jun 24 15:51 /usr/local/lib/firefox/libxul= .so If anyone has any benchmarks comparing the two optimization levels for www/firefox I would be interested to take a look. (And please indicate Fire= fox version, arch, cores and memory size where you ran the test.) Taking a quick peek at about:buildconfig on Android and Fedora Linux, they = are using -Oz with LLVM/Clang5 and -O2 with GCC7 respectively. --=20 You are receiving this mail because: You are the assignee for the bug.=
