It might be worth removing the XSHM code paths. On recent versions of X and with a graphics card from after about 1995, using this code is likely to be slower, because it stops the X server from storing images in VRAM, so generates a lot more redundant copying across the bus. > I get those both on FreeBSD and OPenBSD where I tried. Indeed, it seems a bit > slow. Slowness is more likely to be due to redundant copying or using synchronous X11 calls than the lack of XSHM.
