I have installed Xorg and WindowMaker on FreeBSD 8.1 i386 on a Intel Core2 Duo 2.8GHz. I see that Xorg is very slow, it uses a lot of CPU for very basic tasks (terminal printout, scrolling windows etc...). The graphic chipset is a 13 years old SIS on a PCI card. I installed the xf86-video-sis driver from the ports and apparently the driver includes the cipset model SIS6326. Attached the Xorg.log produced at startx (it is too much text to post it within the message). Any idea about the reason of why Xorg is running so heavily and badly?
