Would it be an idea to create a "Lilypond Benchmark" webpage, small, 
interesting, and useless ;-) This webpage would show a list with the following 
info:
1. Hardware / Processor type
2. Platform / OS
3. Lilypond version 4. The benchmark result: I suggest to give te time needed 
to "make" the (at least in this mailinglist) already famous "Reubke Psalm 94" 
score.

The website should have a simple interface where Lilypond users can enter their 
results and show a list sorted by results. On linux it is easy to measure the 
time using the "time" command.

Would be interesting to see results with relatively old computers as well as 
the newest i7 speeddevils ...

Lilypond does benifit a lot from this fast new processor technology. Speed is 
not Lilypond's strongest point. Other, less powerful but still quite good, 
text-to-musicscore commandline programs like mup (shareware), abcm2ps, and pmw 
are MUCH faster. Even on my ancient Atari computer running at 32 MHz, I could 
run these programs with reasonable speed. But there are several other reasons 
why I prefer and use mostly Lilypond now.

If one day computers will be too fast to give reliable results, we can always 
change the benchmark test by repeating the same test 10 or 100 times :-)

There have been some individual postings on this subject, but a small dedicated 
website would be nice. An extra page on the normal Lilypond homepage maybe ?

I'm not a very capable webpage designer. Any volunteers ?
