i have just tried 5 different versions of the Flash plugin and i cannot reproduce this (flash games are still smooth and acceptable even with the system significantly overloaded with 5 infite loops or with a kernel build), so it would be nice if you could help me debug this problem. The last version that worked for you was v11, correct? The biggest v11 -> v12 change was the yield workaround, and while testing your workload i also noticed that all Flash versions except the latest one (9.0 r31) use sys_sched_yield() quite frequently. So it would be nice to know which plugin version you are using (and which Firefox version): you can check that by typing about:plugins into firefox. Furthermore, could you also try the following tune: echo 0 > /proc/sys/kernel/sched_yield_bug_workaround and this: echo 2 > /proc/sys/kernel/sched_yield_bug_workaround if none of this changes behavior then please send me the output of the following: strace -ttt -TTT -o strace.txt -f -p `pidof firefox-bin` < reproduce the lag in firefox > < Ctrl-C the strace > and send me the strace.txt file (off-line, it's going to be large).
