Hi, why don't you use JMeter? 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.

Grrr... a pox on gmail ajax mode. It told me these did not go out. A resource leak is held by a memory leak. Ruben Laguna just posted this on lucene's java-dev and I've paraphrase it: Take a memory snapshot with JConsole -> dumpHeap [1] and the analyze it with Eclipse MAT [2]. Find the biggest ob

Two different points: Checking once a minute should be sufficient. Also, when I did this instead of pulling a file or doing the 'ping' feature, I did a search of a non-existent fwildcard field "bogus_s:test". The point being to make sure that the Lucene part could actually talk to its index. It sh

Add &debugQuery=true to your URL, look at the parsed query in the debug output to see if things changed there between the two qf values, and then take a look at the score explanations in the debug output. Erik On Apr 10, 2010, at 6:51 AM, Mark Fletcher wrote: Hi, I use *dismax* an
