One big problem with the PostgreSQL and MySQL numbers is that they don't use pooling. I found a simple example of adding that to the PostgreSQL code and done so, though I'm still hunting for a MySQL example :P As far as CouchDB I'm using Richard Newman's nice clj-apache-http library which is a wrapper around Apache HTTP Client. It reuses connections by default. However Iooking into this some more, the connections might still be the bottleneck - I'm looking into using multithreaded client connection manager. Will be interesting to see what numbers come up after that. If the whole premise of the blog post turns out to be flawed at least we have a page documenting the basics of how to use Clojure with several dbs ;) David -- You received this message because you are subscribed to the Google Groups "Clojure" group.
