Multi Core - Max Core Count Recommendation

[Ryan Peterson <OC...@yahoo.com>]

I'm trying to see if anyone has any recommendations on the maximum number of cores that should be used within Solr. Is there significant overhead to each core? Should it be 10 or less, or is 100 or 1,000 cores acceptable.

Thanks,

Ryan

it depends!

yes there is overhead to each core -- how much it matters will depend  
entirely on your setup and typical usage pattern.

sorry this is not a particularly useful answer.

I think the choice of how many cores will come down to your domain  
logic needs more then hardware.  If you are able to put things into a  
single index and get the performance you need, it will just be easier  
to deal with.
