Subject Re: Upgrade to Solr 1.4, very slow at start up when loading all cores
Date Wed, 13 Oct 2010 22:24:06 GMT

just update on this issue...

we turned off the new/first searchers (upgrade to Solr 1.4.1), and ran
benchmark tests, there is no noticeable performance impact on the queries we
perform comparing with Solr 1.3 benchmark tests WITH new/first searchers.

Also the memory usage reduced by 5.5 GB after loading the cores with our
data volume by turning these static warm caches off.

We will take this approach in our production environment but meanwhile I am
curious if this issue will be addressed: it seems the new/first searchers do
not really buy any performance benefits because it uses so much memory,
especially at core loading time.

thanks
Renee
