Also I noticed that sometimes you use random() that is not ANSI standard instead of rand() and INT_MAX and CHAR_MAX instead of RAND_MAX.
Fixed thanks again :)
You are welcome! ;)

And why in strcmp reported alighnments are -1 and 0?
Where exactly do you mean?
I'm sorry it was pos and type, not al_src and al_dst...
Anyway I didn't understand how strcmp may be visualized in one graph...

I've just prepared some graphs from my PowerBook G4 1.67 GHz (for bmove512, memcpy, memset, strcpy, strlen):

Well, if I got all the cases it would need many special graphs, but I only included the case where comparing equal strings. Perhaps I should include more graphs :-/

Wow, the G4 at that speed performs very nicely. If you could send me the CSV data, I'd gladly include the charts in freevec.org with a link to your blog :)

Thanks! This is archive with CSVs, GIFs and sqlite3's benchmarks.db (and also dumped SQL). I run these benchmarks only for 6 functions (including strcmp, but this one was not good probably because of my random.dat had zeros sometimes and I didn't render image for it):

http://shaos.net/blog/files/g4_1670_tests_080425.zip

Later I will publish the same tests for PowerMac G4 400MHz and will run full benchsuite from your SVN on PowerBook G4 1.67GHz.

The same functions (bmove512, memcpy, memset, strcpy, strlen) on my PowerMac G4 400MHz:

Original data files: http://shaos.net/blog/files/g4_400_tests_080426.zip

P.S. On my and your data I see strange peak for G4 vectorized unaligned (!) strcpy for size 6144. Why is it so strange?

More than 2 days (and nights ;) of running benchsuite on my PowerBook G4 1.67 GHz:
