Hi, I agree with Jean-Sebastien. JMeter is great! The threads in my test plan are configured to use an "Access Log Sampler". This allows you to feed your production requests through JMeter, simulating production traffic. When I launch the test, it has access to about 3 million production queries. I also use the "user defined variables" in my test plan so I can customize different parameters at runtime.

It would give you greater control over the tests you wish to make. It has many different samplers that will let you run different scenarios using your existing set of queries. ab is great when you want to evaluate the performance of your server under heavy load. But other than this, I don`t see much use to it. JMeter offers many more options once you get to know it a little. good luck ----- Original Message ----- From: "Blargy" <zman...@hotmail.com> To: <solr-user@lucene.apache.org> Sent: Friday, April 09, 2010 9:46 PM Subject: Benchmarking Solr > > I am about to deploy Solr into our production environment and I would like > to > do some benchmarking to determine how many slaves I will need to set up. > Currently the only way I know how to benchmark is to use Apache Benchmark > but I would like to be able to send random requests to the Solr... not > just > one request over and over. > > I have a sample data set of 5000 user entered queries and I would like to > be > able to use AB to benchmark against all these random queries.
