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
