XputPutImage is one of the few Xlib calls with potentially a huge argument. There are three places for bottlenecks: (1) TC/IP chopping. For example, our Convex computer will only ship 8K bytes at a time and mess up internet XPutImage commands. (2) Socket limits. Xlib arguments pass through UNIX sockets in most implementations. (3) XPutImage chopping. I notice the DEC-3100 and SONY servers split an image into 64K chunks, but the Sun server does not.
