Benchmark File_Passwd crypt_apr_md5()

Hi, Sorry for the many messages, want to open a new thread as the old is hijacked and became enormous. I benched out the 2 versions of File_Passwd: calculating and comparing 100 random length and content plaintexts. the script: http://toggg.com/file_passwd/perf.phps.html No return values differences so it's BC certainly. Here the profiling on my poor P3-500 FC2: +--------+-----------------+------------+------------+ | Method | Netto Time (ms) | Time (ms) | Percentage | +--------+-----------------+------------+------------+

| Origin |       31,314.98 |  31,314.98 |      82.68 |
| Ants   |        6,371.73 |   6,371.73 |      16.82 |
| Global |          188.37 |  37,875.09 |     100.00 |

+--------+-----------------+------------+------------+ _Resource usage_ Array // 0=number of calls, 1=ru_utime, 2=ru_stime, 3=ru_minflt ( [Origin] => Array

      (
          [0] => 100
          [1] => 30.928295
          [2] => 0.015997
          [3] => 211
      )

[Ants] => Array

      (
          [0] => 100
          [1] => 6.287044
          [2] => 0.003
          [3] => 9
      )

) ru for time give same ratio as Benchmark::Profiler(). Means 5 times quicker, but sure better on powerfull machines :( I took this last Passwd.php.diff2 from ants to patch File/Passwd.php You can find RUM on http://pear.php.net/pepr/pepr-proposal-show.php?id=189 à+ -- bertrand Gugger (toggg) Ants Aasma wrote: > Michael Wallner wrote: > >> <plug> >> Well, sorry for jumping in, but would you mind looking at >> File_Passwd::crypt_apr_md5()? ;-) That would definitly need some >> reasonable optimization... it takes about .25s for one passwd. >> </plug> > > Ok, here you go, diff against File_Passwd 1.1.2 > http://www.hot.ee/stepz/Passwd.php.diff > Old one: 83ms > New one: 8.3ms :) > I could squeeze another 60% of performance out of it at 5.1ms by > taking the version check out of the main loop, composing the md5 > argument inline and taking the concatenations out of the loop, but > that looked godawful.
