Performance regression between 4.3.0 and snapshot version.
Bugzilla #434 shows a x11perf regression test between 4.3.0 and a rather current CVS versions. The performance of some tests has gone down by 20% for a specific test, some other tests have suffered a performance penalty of 3%. There may be a simple explanation for this however I can't find it right now. Any idea? Egbert. === Cut from Bugzilla #434 === Yes! Just done all tests with : 4.3.0 vanilla and CVS (as a few days ago, with the O_SYNC flags removed) both compiled on the box. See attachment for the full output of x11percomp.

In the later 4.3.99.x series the BIOS now works for him, but unfortunately the BIOS makes some more conservative settings for the accelerator engine in the savage.

The Savage BIOS doesn't touch the graphics accelerator at all -- only the video timings. The accelerator is managed entirely in the driver.

But I don't really understand why I saw only few performance problems and almost all other tests are good (and several are even very very good wrt to 4.3.0. Anyway I'll post the result here and on bugzilla. Bye Manu pgp0.pgp Description: PGP signature

Re: Performance regression between 4.3.0 and snapshot version.
Looks like a code generation issue. P4's will do that sometimes when you change the alignment of particular functions/structures. The graphics driver probably has nothing to do with it since the worst regressions don't involve graphics. Mark.
