I'm not sure how relevant the benchmark is, since all it tests in
throughput of database insert operations. The combination of insert,
update, delete and selects with more even distribution of operations
will be much more helpful, but much harder to test.

There's also the lighter-weight MiniCollectionPoolManager. See

Hello David,

I'm interested to see what will be CouchDB numbers when there are
indexes on the data.
In my experience, this is a speed killer.
All the best,

Here are my examples for mysql and postgres using commons-dbcp. They
are exactly the same except for the connection info. Might want to
play around with the initial,min,max size properties.

I'd post a example clojure usage but I'm afk atm. The lib's BasicDataSource
is probably all you'd need.
Depends on Commons pool. Just pla
I think what you're doing is great. I understand you're using ab for
these tests, right? What are the actual settings that you are using?
Also, I'd like to mention that what these tests are showing is the
behavior of the server under constant load (constant frequency in the

Hi David,
Out of curiosity, how are these tests connecting to the database,
especially in the cases of MongoDB and CouchDB? In the case of CouchDB
you're clearly using HTTP in a way that it creates one connection per
request, I believe. In the case of MongoDB, the driver provides a
connection pool
Some benchmarks thoughts on various databases + aleph.
