I think R12B-3 didn't properly fsync data on OS X, so the speediness
had a possible side effect of data corruption. Jan submitted a patch
to the OTP team and it was applied in a later version. That might be
one reason for the difference ...

I'm not sure I did, so I deleted the install completely, re-installed
and am running via ./utils/run so I'm pretty sure there's no detritus
hanging around.
After re-running the test suite 3 times the avg run time on 0.9.1 was
47s and and on 0.10 (804278) was 31s.

Paul,
That's most odd. This is the first i've heard of a performance drop
after upgrading Erlang. When you re-built CouchDB did you make sure
that there weren't old beam files in the build directory?

Hi
I've been behind the curve in my otp version, running R12B (5.6.3)
until just now.
Using R12B, the 0.9.1 test suite ran to completion in about 12s.
I've just upgraded to R13B01 (5.7.2) and now the 0.9.1 test suite
takes about 50s - 60s to complete. This is a big difference. Is it
expected or have I got problems?
I'm running OS X 10.5.8 and simply ran ./configure without any flags
when building both Erlang and CouchDB. I re-ran ./configure and make
for CouchDB after upgrading Erlang.
Many thanks
Paul
