Subject Re: Replacing text fields with numeric fields for speed
Date Fri, 23 Jul 2010 12:33:54 GMT

just for my interests:
does apache bench sends different queries, or from the logs, or always
the same query?
If it would be always the same query the cache of solr will come and
make the response time super small.

I would like to find a tool or script where I can send my logfile to solr
and measure some things ... because at the moment we are using fastbench
and I would like to replace it ;-)
