Everything you are describing smells like some kind of Disk/IO throttling
behavior external to Solr.
Nothing you've identified below should be particularly "slow" and it
certainly shouldn't get orders of magnitude slower for subsequent
SolrCores in rapid succession, even as those cores are sm
Hi again,
After digging through Solr and Lucene code some more and instrumenting it with
lots of timing I can see three main culprits when it comes to replicating data
from 3 cores around the same time:
Lucene IndexWriter's getFieldNumberMap
Have often seen times up around 30 seconds but what is
probably the easiest way to get input on this one is to find what seems to
be the cause of what looks like global lock behavior and then mention that
cause here.
No, you wouldn't expect replication to take turns and go one at a time, but
you're more likely to get relevant feedback if you can point
Hi,
Before I proceed to create a Solr Jira issue I'll ask for some feedback here
first. I did start a thread on the users mailing list a few days ago about this
topic without any relevant feedback
