Joel:
I did a little work with SOLR-9296 to try to reduce the number of
objects created, which would relieve GC pressure both at creation and
collection time. I didn't measure CPU utilization before/after, but I
did see up to a 11% increase in throughput.
It wouldn't hurt my feelings at all to ha
Thanks Joel.

It sounds like your scenario, is around 25 queries per second, each pulling
entire results. This would be enough to drive up CPU usage as you have more
concurrent requests then CPU's. Since there isn't much IO blocking
happening, in the scenario you describe, I would expect some pretty busy
CPU's.
Hello:
Any follow up?

Followup question: You say you're indexing 100 docs/second. How often
are you _committing_? Either
soft commit
or
hardcommit with openSearcher=true
?

Thanks Joel
here is the information you requested.
Are you doing heavy writes at the time?
we are doing write very frequently, but not very heavy, we will update
about 100 solr document per second.
How many concurrent reads are are happening?
the concurrent reads are about 1000-2000 per minute per
Are you doing heavy writes at the time?
How many concurrent reads are are happening?
What version of Solr are you using?
What is the field definition for the double, is it docValues?

Hello:
We are using export handler in Solr Cloud to get some data, we only
request for one field, which type is tdouble, it works well at the
beginning, but recently we saw high CPU issue in all the solr cloud nodes,
we took some thread dump and found following information:
java.lang.Thread.
