1.4 -> 1.5.1 performance regressions

Hi, I noticed some performance regression moving to a newer system with Xserver 1.5.1 from an 1.4 system with both XAA and EXA. As a benchmark I am using GtkPerf [0] with "gtkperf -a -c500" without compiz on a MacBook Pro with a Radeon RV530. While I noticed some improvement going from 1.5 to 1.5.1, 1.5.1 is still slower than 1.4. This may be related to recent report of slowness (thread http://lists.freedesktop.org/archives/xorg/2008-October/039164.html). My reference systems are: 1) 1.4 system: installed system with Ubuntu 8.04 with xserver 1.4, kernel 2.6.24 + backported -ati driver, radeon drm module, libdrm, mesa (used many recent git version); 2) 1.5.1 system: LiveCD Ubuntu 8.10 with xserver 1.5.1, kernel 2.6.27-rc9 recent -ati git snapshot, radeon drm module from kernel, libdrm 2.3.1, mesa 7.1. Does someone is able to reproduce this regressions, maybe changing only the xserver? Is there some known bug?
