I tried oprofile, here are top 3 log entries for current git version compiled
with default options on 64-bit Ubuntu 10.10:
CPU: Core 2, speed 1998 MHz (estimated)
Counted CPU_CLK_UNHALTED events (Clock cycles when not halted) with a unit mask
of 0x00 (Unhalted core cycles) count 100000
samples % image name app name symbol name
752008 31.3913 libfontconfig.so.1.4.4 libfontconfig.so.1.4.4
/usr/lib32/libfontconfig.so.1.4.4
733152 30.6042 no-vmlinux no-vmlinux /no-vmlinux
83350 3.4793 libfreetype.so.6.6.0 libfreetype.so.6.6.0
/usr/lib32/libfreetype.so.6.6.0
Compiling --without-fontconfig makes it visibly faster, and top 3 entries are:
samples % image name app name symbol name
201311 17.7830 libfreetype.so.6.6.0 wine-preloader
/usr/lib32/libfreetype.so.6.6.0
99397 8.7803 no-vmlinux Xorg /no-vmlinux
92871 8.2038 anon (tgid:23316 range:0x32f1000-0x3ef0000) wine-preloader
anon (tgid:23316 range:0x32f1000-0x3ef0000)
Sorry for lack of vmlinux and debug symbols, I don't know where to get them. I
haven't found debug packages in the repositories for ia32-libs or my current
kernel. Anyway, I guess we should look closer at font rendering, as it seems to
be the main problem.
