Hi have a LAMP stack connecting to a Solr 3.6.1 server running on CentOS 6.3. While benchmarking my app, I noticed sudden spikes in the time taken for PHP to send a search query to Solr and getting the results back.
This time is usually about 20-40 msec and Solr's
QTime is typically 0-30 msec.
My benchmark results:
Start function msec Creating the query 2.50196456909 msec Executing query and getting results (PHP & Solr) 37.4531745911 msec \->Executing query (as reported by Solr QTime) 21 msec Processing Solr results
Problem: However, sometimes this step
Executing query and getting results (PHP & Solr) will shoot up to 2000+ msec, and Solr continues reporting 0-30msec
QTime. This makes me suspect that there may be a problem in the connections between PHP/Apache and Solr.
How can I determine if this is true, or make this connection better?
