I ran a "nice make -j3 bzImage" on 2.6.9-test3-mm1 in order to compile 2.6.0-test3-mm2 on my dual celeron.
While waiting I played cuyo, a lightweight game similiar to tetris.
This mostly behaved as expected, with a responsive game. But mozilla (on some other virtual desktop) occationally refreshed its page, causing several seconds with jerky response in the game.
This is wrong for two reasons: 1. There should be enough cpu with two processors, one running the game and another the heavy mozilla stuff. The make was niced after all. No guessing, I told it explicitly.
2. The game has very interactive behaviour, it uses 4-10% cpu and cause X to use about 20%. Mozilla may have been idle for a while, getting "interactive". But it shouldn't remain interactive for so long, it sat at 100% till it went idle again.
X runs with elevated priority, (std. debian testing setup) but that shouldn't matter - X only used 20% and that was for the game and two xterms. Mozilla wasn't visible at all.
