Window buffer compression and 10.1.1
For all those who enabled window buffer compression, the file /Library/Preferences/com.apple.windowserver.plist 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 "#" done But there's no real cpu use with normal terminal output.
Strange...
On my G4/350, here's the TOP output during my little experiment (a simple "ls -al" repeated 100 times):
PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE VSIZEAnd 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.
Window buffer compression and 10.1.1
After upgrading to 10.1.1 windows compression is still enabled (the lines I added to com.apple.windowserver.plist are still there, and Quartz Debug still show's "C" next to compressed windows. |
