I have a 1.83 GHz T2400 Core Duo with 2GB in my Inspiron 9400. I do a lot of math intensive simulation that run for hours. I was running Windows and hit the memory limitation (could only access 1 GB for the application) so switched to Ubuntu. In Ubuntu, the application could access 1.7 GB, but compared to Windows I had about a 33% speed reduction.
I noticed in Linux I was stuck at 1.0 GHz during simulations... cat /proc/cpuinfo I just wanted the problems fixed... so this is what I did: cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies output was: 1833000 1333000 1000000 (the available frequencies I can set my cpu frequency to) Then I set the cpu frequency to 1833000: cpufreq-set -f 1833000 Problem solved for me.... Now Linux simulations are 20% faster than Windows This is just a solution of how to get around it until a decision is made how how to fix this issue. -- [GUTSY] cpu freq scaling not working anymore https://bugs.launchpad.net/bugs/132271 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
