I recently re-built emacs 23 from cvs and there's a noticeable delay in many
repainting operations. Typing is sluggish and redrawing a buffer when
switching to it is noticeably slow.
So I tried to measure the difference. I started two versions of emacs with
--no-init, loaded nothing, and immediately ran elp-instrument-function on
"ibuffer". Here are the results:
emacs(GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600) of 2008-02-20 on
U0103223-XPA)
Function Name Call Count Elapsed Time Average Time
ibuffer 1 0.0 0.0
GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600) of 2008-05-12 on U0103223-XPA
Function Name Call Count Elapsed Time Average Time
ibuffer 1 0.032 0.032
I ran elp-instrument-function again and got:
ibuffer 1 0.047 0.047
The time difference is very small, but with a loaded up emacs config the
time becomes very noticeable.
I built emacs on windows-xp using cygwin(-mno-cygwin however), ming32-make.
Both versions of the build where 'configured' the same:

reassign 233 emacs,w32
thanks
It seems that the performance issues are resolved by using uniscribe's
built in caching for glyph encoding, and avoiding explicit encoding in
the gdi backend.
