I can confirm this on a laptop AMD Turion X2 RM-70, Intrepid AMD64. At first I was mesmerized to find Avidemux running 4 times faster in Vista than in Ubuntu on the same machine. Then I realized it was not using all its cpu power, so I changed the cpufreq governor to 'Performance' and it worked as expected.
However, I consider this to be a workaround and not a desired behavior: I don't want to fry my laptop by letting it run all night long at 100% just because I forgot to change cpufreq back to normal. $ uname -a Linux cpu3 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux -- ondemand governor does not use maximum frequency under load https://bugs.launchpad.net/bugs/122993 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
