I'm also interested in hearing from more people using multi-threaded
applications.
I applied the patch to my old core duo p7570 running CURRENT/amd64.
Firefox is more responsive and youtube videos, previously impossible to
watch, run smoothly, even in full screen. Sumultaneously did some photo
editing work in gimp, ran gigabyte sized file transfers with sftp and took
a CVS update on ports without any hiccups. Browsing in Firefox remained
smooth although I heard a few glitchs in audio playback when scrolling
while a busy page was still loading, with load average hovering around
2.5 with 58 processes and 138 threads at the time. Otherwise smooth
sailing, very nice.
