Thanks yonik .. will consider Jconsole

It really depends on how much stuff is cached, what fields you facet
and sort on, etc.
It can be easier to measure than to try and calculate it.
Run jconsole to see

Thanks Lance for the clear explanation .. are you saying we should give
solr JVM enough memory so that os cache can optimize disk I/O efficiently ..
that means in our case we have 16 GB index so would it be enough to
allocated solr JVM 20GB memory and rely on the OS cache to optimize disk I/O

below is the solr version info :-

Solr Implementation Version: 1.3-dev
Lucene Specification Version: 2.3.1

Long times to stream back the result to the client could be due to
- client not reading fast enough
- network congestion
- r
So I need someone with better knowledge to chime in here with an opinion
on whether autowarming would help since the whole faceting thing is
something
I'm not very comfortable with...

@Israel: yes I got that point which yonik mentioned .. but is qtime the
total time taken by solr server for that request or is it part of time
taken by the solr for that request ( is there any thing that a solr server
does for that particulcar request which is not included in that qtime
bracket )

Also, how about a sample of a fast and slow query? And is a slow
query only slow the first time it's executed or every time?

Thanks for the quick response
@yonik
>How much of a latency compared to normal, and what version of Solr are
you using?
latency is usually around 2-4 secs (some times it goes more than that
) which happens to only 15-20% of the request other 80-85% of
request are very fast it is in milli s
