RE: [solr-user] Upgrade from 1.2 to 1.3 gives 3x slowdown

[Grant Ingersoll]

Hey Fergus,

Finally got a chance to run your scripts, etc. per the thread:
http://www.lucidimagination.com/search/document/5c3de15a4e61095c/upgrade_from_1_2_to_1_3_gives_3x_slowdown_script#8324a98d8840c623
I can reproduce your slowdown.

One oddity with rev 643465 is:

On the old version, there is an exception during startup:
Mar 28, 2009 10:44:31 AM org.apache.solr.common.SolrException log

I see two things in CHANGES.txt that might apply, but I'm not sure:
1. I think commons-csv was upgraded
2. The CSV loader stuff was refactored to share common code

I'm still investigating.
