There have recently been updates for the kernel, Firefox and Seamonkey. Since then, my computer has run much better, though still not as well as with 11.0. James Knott wrote:
I have previously mentioned the extremely poor performance of my main computer, since updating to openSUSE 12.1. On this computer, System Monitor shows CPU history solidly at 100%, only occasionally dropping. Memory and Swap shows memory at 1.5 G of 2.9 and swap at 0.04 of 8. Sometimes the computer bogs down do much that it's essentially unusable. It's a 64 bit AMD CPU & 3 GB of memory and it ran 11.0 very well. Below is a recent "top" capture showing significant amounts of CPU and memory being used by plugin-container and Xorg. I have disabled flash in Seamonkey and Firefox browsers. I have also tried both NVidia and Nouveau video drivers. I even tried turning off PAE support in the BIOS, as it's not necessary with 64 bit and also less than 4 GB of memory. Any idea as to what's causing the performance hog? What I can check? A notebook, also running 12.1, does not exhibit this behaviour. On it, Xorg is running about 3% CPU and 0.5% memory (4 GB installed). Plugin-container doesn't seem to be running on that computer. Can it be turned off? If I reboot the computer or restart the desktop, performance is temporarily better, though not what it should be.
tnx jk
