To test with pooled DB connections I thought I'd mention Apache Commons dbcp. Its a generic connection pool library that could be used for any jdbc connection.
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 place both jars on the classpath. http://commons.apache.org/dbcp/ Allen On Jul 10, 2010 12:47 PM, "Toni Batchelli" <tbatche...@gmail.com> wrote: 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 arrival times of the requests, and constant load attached to each request). This is not what happens in reality though, and servers that do well under a constant distribution of requests might not do that well (at all) under a Pareto distribution of both arrival times and load (a real load that a server gets is very similar to a Pareto http://en.wikipedia.org/wiki/Pareto_distribution). Under a Pareto load a well crafted event-based server that has bounds on the number of threads used (and maybe other resources) might significantly outperform a 1-thread-per-request server. Unfortunately, I don't think ab can test these scenarios. I built a tool sometime ago while working at UCSB that would do exactly this. I will look into whether I can dig it out and opensource it.
