Subject Solr 4.2.1 higher memory footprint vs Solr 3.5
Date Mon, 03 Jun 2013 16:34:05 GMT

Using the same schema for both Solr 3.5 and Solr 4.2.1 and posting the same
data to both these server,  and the memory requirements seem to have gone up
sharply during request handling.
. Requests come in at around 200QPS.
. Document sizes are very large but that did not seem to be a problem with
3.5 (Lots of multivalued fields with large array lengths.)
Could you help me understand what change in SOLR 4.2.1 would attribute to
this higher memory requirement?

Also, in a different test, I ran a query to just get a list of all unique
ID's via a single query and no load and I see it complete in <500ms however
the time it takes to ship the data back to the client seems to be very
large.  Any idea what could be causing this behavior?

Would appreciate any help.
