X11, Window Managers "Maybe I'm just naive, but designing a graphics API such that all image data had to be sent over a socket to another process every time the image needed to be drawn seems like complete idiocy. Unfortunately, that is precisely what the X Window System forces a program to do, and exactly what Cairo does when drawing images in Linux - a full copy of the image data, send to another process, no less, every time it is drawn. One would think there would be some room for improvement. Unsurprisingly, others felt the same way about X, and decided to write an extension, Xlib Shm or XShm for short, that allows images to placed in a shared memory segment from which the X server reads which allows the program to avoid the memory copy. GTK already makes use of the XShm extension, and it seems like a good idea to see if Gecko couldn't do the same."

RE[5]: Overstated conclusion

Member since:

I thought his point was the 10baseX saturates quicker, given X being more bandwidth hungry, thus causing higher latency.

It takes a lot to saturate 10mbit. Watching a movie or playing software rendered Quake will do it. But browsing the web with Firefox/Cairo? Not even close. Many of my users started out on 10baseT some years back and the difference is not even detectable when doing normal business desktop things.

Yes, if what you are doing is inherently high bandwidth the extra bandwidth of 100baseT will help. Otherwise, latency is the determining factor.
