solr performance tuning issue

[ve...@bt.com]

Hi users,

Could you please help us on tuning the solr search performance. we have tried to do some PT on solr instance with 8GB RAM and 50,000 record in index. and we got 33 concurrent usr hitting the instance with on avg of 17.5 hits per second with response time 2 seconds. as it is very high value .


we are looking for 0.5 sec responce time for the same.

Hello,

What's you OS/cpu? is it a VM or real hardware? which jvm do you run? with
which parameters? have you checked GC log? what's the index size? what's a
typical query parameters? what's an average number of results in the
query?  have you tried to run query with debugQuery=true during hard load
time and looking into per component dump? have you tried to do the same in
a calm time, what's the latency in this case? these are an mandatory
initial seed for the type of question which you are asking.

Good Luck
