Perhaps a really silly question, but... Is your batch job sending
queries serially? In which case this is understandable and would be
sensitive to the lower hit ratios in your caches.
If this is the case, you still won't get 2x the performance with two
servers, I'm guessing your total time to run
Hi guys,
Thanks a lot for the cogent feedback, much appreciated. I'll group my answers
in one message.
1- (Charlie): regarding the type of queries I make: here is a typical one; it's
fairly vanilla, no faceting or anything fancy.
q=+((titleStart:"was sixteen")(subTitleStart:"was
sixteen"))+(p
Just to check: your index is NOT sharded, correct?
Assuming not sharded, is it SolrCloud? If not SolrCloud, how are the
indexes kept in synch? Master/slave? Manual copy?
But for an unchanging index, this is definitely odd.
Best,

Is this a production log of queries, with lots of repeats? If so, you may be
seeing the normal effect of lower cache hit rates.
Check the hit rate for the query result cache in the two setups. With a single
machine, the second occurrence of a query will be a cache hit. With two
machines, it wil

Hi Toke,
thanks for your suggestion - definitely an interesting idea. But unfortunately
no, no indexing job is running; those are static indexes being queried. The
execution time is also very consistent in each condition, I did quite a few
tests.
