Subject Need Debug Direction on Performance Problem
Date Sat, 17 Jan 2015 04:22:56 GMT
Hi all,

We have single solr index with 3 fixed fields(on of field is tokenized with
space) and rest dynamic fields(string fields in range of 10-20).

Current size of index is 2 GB with around 12 lakh docs and solr
nodes are of 4 core, 16 gb ram linux machines.

Writes performance is good then we tested one read query(In select query we
are applying filter criteria on tokenized field & reading only score field,
no grouping/faceting) in two setups :

*Setup1 : *Single Node Cloud with shards=1, replication=1
In this setup whole 12 lakh docs are on same machine. Our filter query
reading
around 10 lakh docs with only score field is taking *1 minutes*.

*Setup2 : *Two Node Cloud with shards=2, replication=1
In this setup whole 6 lakh docs on node1 and 6 lakh on node2. Our same
filter query reading around 10 lakh docs with only score field is taking *114
minutes.*

Please guide us what can be possible reasons of degradation of
performance after sharding of index. How can we check where solr server
is taking time to return results.

Thanks
Naresh
