Well i did another test. Copied the Index files from perf lab to Dev machine
which has Solr4.1
Now ran solrmeter to generate load on Dev server. We were able to drive the
QPS upto 150 with CPU on avg 35%. but the same index is generating 100% CPU
at 1 QPS in perf lab.
On a side note. has "fl" parameter to do anything with this? coz with my
test using solrmeter i used fl=*,score and q=masterId:xxxx. Where as in perf
lab they have fixed 10 field names in "fl".
I have seen some anectodal evidence that including 'score' in fl makes
things very slow -- people mentioning things in IRC and the mailing
list, not sure which because they all blend together in my mind.
I don't think any of those claims have been verified, so you might try
removing the fl parameter from the system where it is set to *,score.
If you see a big performance jump, then there may be something to it.
