2. libX11:

Increase libX11 default buffer size (and provide a new env variable as
tuneable"
As noted in the bug, we made a similar change in Solaris Xsun a while ago.
This change increases the amount of requests/data that can be buffered in
the library before a flush to server has to be done. For many apps it makes
little difference, since they flush on their own, either explicitly or because
they made a request which requires response. For some though, it does reduce
the number of times you have to context switch when sending large numbers of
non-interactive requests or requests with large data to the server. We found
on a local connection it gave a boost around 1% to x11perf/Xmarks.
We also found a similar benefit in increasing the BUFSIZE used in
xc/programs/Xserver/os/{osdep.h,osinit.c,io.c,lbxio.c} for the buffer the
Xserver receives the data from the client. (Currently 4k.)
