Window buffer compression and 10.1.1
Authored by: jnm on Nov 16, '01 03:15:13PM
For all those who enabled window buffer compression, the file /Library/Preferences/ is simply replaced during upgrade to 10.1.1 (the date of this file on my computer is Nov 15, which is the date I did the upgrade). This to say the window buffer compression modifications aren't there anymore ! Maybe they ar not needed anymore, who knows ? ;o)

Anyway, on my Dual 450 G4, 512 Mb there's indeed a really impressive speed reduction when I do a nice little loop like this one (sorry, it's bash !) in a minimized Terminal window :

while true; do
echo -n "#"

But there's no real cpu use with normal terminal output.

On my G4/350, here's the TOP output during my little experiment (a simple "ls -al" repeated 100 times):
9967 Dock 73.2% 0:07.80 3 110 101 3.30M- 11.4M 7.36M- 69.2M
9985 top 12.3% 0:04.06 1 14 15 304K 352K 544K+ 1.45
9985 top 6.3% 0:03.88 1 14 15 304K 352K 540K- 1.45M
etc etc etc
And this is just after a reboot, too. I have NOT re-enabled window buffer compression; I'll try that later and see what happens. -rob.

After upgrading to 10.1.1 windows compression is still enabled (the lines I added to are still there, and Quartz Debug still show's "C" next to compressed windows.
