Subject Performance drop after upgrading erlang
Date Fri, 14 Aug 2009 15:44:35 GMT

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
