I have to respond to this performance statement. Here on a MacIIfx with
16 M memory, I have both Apple's commercial MacX for A/UX 2.0 and MIT's
standard X11R4 (with patches 1-19) distribution compiled under gcc
1.37.91. In doing large nos. of vector draws on a Tektronix xterm, I
roughly gauged the MIT server to operate twice as fast as the MacX server.
So I ran x11perf on each server in one-bit mode to check it out.
Here are the results of the first few x11perf tests:
Repetitions/sec
Test Name MIT MacX Factor
--------------------------------- --- ---- ------
Dot 97300 26800 3.6
1x1 rectangle 28200 12600 2.2
10x10 rectangle 14700 9120 1.6
100x100 rectangle 1320 1000 1.3
500x500 rectangle 108 36 3.0
1x1 stippled rectangle 24800 10600 2.3
10x10 stippled rectangle 13000 7310 1.8
100x100 stippled rectangle 944 792 1.2
500x500 stippled rectangle 62 32 1.9
1x1 opaque stippled rectangle 7000 6390 2.6
10x10 opaque stippled rectangle 5290 2500 2.1
500x500 opaque stippled rectangle 68 25 2.7
These figures support the rule my fingers already knew: don't do
graphics under MacX; use X11R4 for that. The beauty is we can have
both; it takes me maybe 30 sec. to switch from X11R4 to the Macintosh
desktop.
