djangobench results (1.4 vs 1.3)

I just completed some runs comparing performance of 1.4 vs 1.3 using
Djangobench. There doesn't seem to be any repeatable significant
regressions or gains except for these two tests:

Running 'url_resolve' benchmark ...
Min: 0.000000 -> 0.000000: incomparable (one result was zero)
Avg: 0.000092 -> 0.000142: 1.5424x slower
Significant (t=-8.211439)
Stddev: 0.00009 -> 0.00010: 1.0696x larger (N = 500)

Running 'url_reverse' benchmark ...
Min: 0.000000 -> 0.000000: incomparable (one result was zero)
Avg: 0.000100 -> 0.000168: 1.6761x slower
Significant (t=-8.269947)
Stddev: 0.00012 -> 0.00014: 1.1812x larger (N = 500)

I don't know if 50% slowdown in these tests are critical. Maybe worth
checking where the difference comes from.

I also compared 1.4 vs 1.3 when USE_TZ was set to on. No regressions
there.

So, nothing really interesting found, which I guess is good news.

BTW are there anybody who is running these kind of tests regularly? I
mean is there any point of reporting these kind of finds, or are they
already known?
