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.
