I use firegl driver from ATI. I know this is not directly related to DRI but still.
I enabled Fast Writes from bios and now I get 440MB/s with ShmPutImage. The real bottleneck seems to be texture downloading with glTexImage2d. The speed I get is 121MB/s. Using glDrawPixels I get 710 MB/s. So I should use glDrawPixels and then glCopyTexImage2d for best performance.
