A while back I had installed couchdb v0.8. Today I installed from the latest
source (reporting 0.9.0a731428-incubating); I've set debuglevel to error.
However, when I run the test suite the 0.9 version is 4 to 10 times slower
for all tests compared to when I run the test suite using the 0.8 version.
There are more tests than in the past, so that should be a factor.
I'm not talking about the total time, I'm referring to the times of
individual tests. Here's my test run using v0.8:

and here are the results when using v0.9 source:

So for example the test recreate_doc, which hasn't changed for months,
takes 345ms using v0.8 and 4406ms using v0.9. That's more than 10 times
slower. Same machine, same erlang host.
There is another thread about document insert rate, which shows the
ways people are benchmarking CouchDB. If you were able to post some
comparative benchmarks of particular operations, so we could see the
difference, I'm sure a lot of us would appreciate it
I'll post my results there, for both couchdb versions.
Cheers,
Lawrence
