Subject Re: Solrconfig clarification: ColdSearcher/MaxWarmingSearcher

Thanks for the clarification and for untangling my questions. :)

I'm in the process of finding out why our snapshot installs take so long to
commit and didn't feel so confident about my settings, thanks.

In terms of long snapshot commits - I've isolated it to long warming times. 
But since the warming query I use is of the same basic layout as "the" query
we do at runtime I'm not sure what to do.  At the moment I'm trying to
isolate where the time is spent, if its just in pre-allocating large arrays
and other data structures like the FieldSortedHitQueue - because my queries
tend to be date sorted...

Index Facts:

1. 22M documents
2. Snapshot installs to slave: 5 minutes
3. Warmup times: ~200-400 seconds hence the backup on warmers

Problem with the backup searchers is that I run my JVM out of heap space if
more than one searcher is warming up int he background.

Continuing to profile commit/warming queries.  Any helpful hints would be
much appreciated.


Cheers,

Jim
