I tested it on a Core2Duo box and software rendering manages to do about 3 frames per second. (although glxgears itself thinks it does ~600 fps) If i start 3 glxgears then they do ~1 frame per second each. This is on Fedora 7 with xorg-x11-server-Xorg-1.3.0.0-9.fc7 and xorg-x11-drv-i810-2.0.0-4.fc7.
