Re: slow indexing when keys are verious

Hi all

We have changed all solr configs and commit parameters that were mentioned
by Shawn,
but still - when inserting the same 300 documents from 20 threads we see no
latency
and when inserting different 300 docs from 20 threads it is very slow and no
cpu/ram/disk/network are showing high metrics.

I am wondering if the problem might be related to the fact that when
inserting different 300 docs from each thread,
the key is the only field that varied whilst the other fields are identical.
So maybe many same values on the other fields for different keys cause the
latency? 

As for latency that is related to doc routing, I don't see where it can
affect us. Is it the zookeeper that might become a bottleneck? 

Thanks!
Gilad
