Folks,
We're running into some performance bottle neck issues while running lucene
search against our indices (approx 1.5 GB in size after optimization), and
the search query seems to block on a sychronized read as follows. Obviously we
can upgrade to the latest as a first step. When Tomcat runs into this, it
stops responding, and is restarted by our monitor software. We ran grinder and
it shows it can support about max 7 queries per second (log also included). Any
ideas how to why it's running into this issue or to improve performance?
Thanks
OSC
