Xft performance with XEmacs 21.5.28 on Mac OS 10.5

Hi,

I recently built (using XCode 3.0 toolchain, on Mac OS X 1.05) XEmacs 21.5.28, targetting X11 with xft. My configure line was:

./configure --with-xft=emacs,tabs,menubars,gauges --with-mule --with-x --x-includes=/usr/X11/include --x-libraries=/usr/X11/lib --with-error- checking=none

This builds, installs, and runs well under Apple's X11 2.0, except for one thing: font redraw is glacially slow! (This is on a 4x2.66GHz Mac Pro...)

I found the thread titled "Xft performance" in the Apple X11-users list, which was started by Eric Knauel on 2003-07-28 (!), but no particular conclusion was reached there.

Since I'm seeing a significant performance problem here with the latest Apple tools and hardware, I'm hoping that I can help to fix it (either in XEmacs or in Apple's X11) by doing some diagnostics on this machine to determine where the problem lies. XEmacs built in a similar way running on e.g. stock Kubuntu 7.10, on significantly slower hardware, does not exhibit this performance problem.

So, what information should I gather (this might be a good way to learn my way around "Instruments"!) _______________________________________________ Do not post admin requests to the list.
