No, it is a stand-alone program. You give it the index directory, the default query field, the number of threads, and the filename of a file that contains one Lucene query per line.hreads. The output is one line: the # fo threads followed by the #queries handled per second. I have a shell script which runs the above with increasing #s of threads. > I couldn't find info about the index format (compound or not) you used.

The index in the benchmarks uses the compound format, with 0% documents deleted. > > Finally, if you end up extending contrib/benchmark, I think just having the > ability to pump the results of that into a gnuplot script would be nice to > have.

Let me finish off what I am doing for my work and I will clean things up a bit, write a little documentation. -Glen > > Otis > -- > Sematext -- http://sematext.com/ -- Lucene - Solr - Nutch > > > ----- Original Message ---- >> From: Glen Newton <[EMAIL PROTECTED]> >> To: java-user@lucene.apache.org >> Sent: Tuesday, June 10, 2008 12:51:41 AM >> Subject: Concurrent query benchmarks >> >> A number of people have asked about query benchmarks. >> >> I have posted benchmarks for concurrent query requests for Lucene >> 2.3.1 on my blog, where I look at 1 - 4096 concurrent requests: >> http://zzzoot.blogspot.com/2008/06/simultaneous-threaded-query-lucene.html >> >> I hope you find this useful. >> >> thanks, >> >> Glen >> >> -- >> >> - >> >> --------------------------------------------------------------------- >> To unsubscribe, e-mail: [EMAIL PROTECTED] >> For additional commands, e-mail: [EMAIL PROTECTED] > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > -- - --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
