Hi,
    As mentioned in my previous post
<http://www.mail-archive.com/solr-user@lucene.apache.org/msg28339.html>  ,
we are experiencing a delay (latency ) for 15 % of the request to solr .
delay is about 2-4 sec sometimes it even reaches 10 sec (noticed from apache
tomcat logs where solr is running , so internal  network issue ruled out).
So to fix the roblem we need to analyze where  solr/lucene is  taking time ,
for that  we need to understand how solr/lucene handles a select query
(what are the methods  being used )   . is there any doc or link which
explains the same in detail ?  . We are planning to change the source code
to log the time each method takes while solr handles a request so that we
can analyze where  solr/lucene is  taking time. I am not sure if this is the
right way (unless if this is the only way  ) . Is there any other way to
analyze where  solr/lucene is  taking time ?

so we need to know two  things :
 1.how solr/lucene handles a select query (link or doc will do ) ?
 2. any way to  anaylse where solr/lucene is taking time  ?

Thanks in Advance,
Bharath
