KernelTrap: Interactivity Improvements Backported

Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers

"By popular request, Con Kolivas has backported Ingo Molnar's earlier interactivity improvements to the 2.4.20 stable kernel. The interactivity patch was first added as an enhancment to Con's desktop oriented patchset in 2.4.20-ck4. I immediately downloaded the patch myself and gave it a try, disappointed to discover it was less responsive than Con's plain -ck4 patchset. By switching tab views in GnuCash I could consistently skip music that was playing with XMMS, something I've rarely experienced since I started using Con's patchset back in September. The only improvement I noticed was that the system responded very well when performing the less-than-scientific 'wiggle test' (grab a window and wiggle it around on the screen quickly).

"Fortunately, 48 hours later Con has released 2.4.20-ck5, adding a host of improvements. I quickly compiled a new kernel with his -ck5 patch and Rik van Riel's rmap15e VM applied, and then booted into an improved desktop experience. I tried really, really hard to get XMMS to skip again on my aging PIII 550, but try as I might, it refused. And the system continued to respond well when performing the wiggle test. Con describes the desktop tuning changes he made:

"'It became clear that even with the interactivity changes audio skipping could occur so I've added some more desktop tuning to this version far less drastic than the previous kernels. The desktop tuning patch just changes a few of the default settings and these are all able to be modified at config or after boot if so desired...'"
