Hi Mark,
Thanks for the reply.
You are right.We need to test first by decreasing the mergefactor and see
the indexing as well as searching performance and have some numbers in hand.
Also after partial optimize with the same mergefactor how long the
performance lasts(both searching and indexing)

Hi Mark,
In the above case , what if the index is optimized partly ie. by
specifying the max no of segments we want.
It has been observed that after optimizing(even partly optimization), the
indexing as well as searching had been faster than in case of an
unoptimized one.
Decreasing the merge fac
Hi Mark,
Thanks for your reply.
What you saying is interesting; so are you suggesting that optimizations
should be done usually when there not many updates. Also can you please
point out further under what conditions optimizations might be beneficial.
Thanks.

I would not optimize - it's very expensive. With 11,000 updates a day, I think
it makes sense to completely avoid optimizing.
That should be your default move in any case. If you notice performance suffers
more than is acceptable (good chance you won't), then I'd use a lower merge
factor. It de
Hi Mark,
We are performing almost 11,000 updates a day, we have around 50 million
docs in the index (i understand we will need to shard) the core seg will
get fragmented over a period of time. We will need to do optimize every few
days or once in a month; do you have any reason not to optimize the
Do a you have something forcing you to optimize, or are you just doing it for
the heck of it?

Hi,
I would like to optimize solr core which is in Reader Writer mode. Since
the Solr cores are huge in size (above 100 GB) the optimization takes hours
to complete.
When the optimization is going on say. on the Writer core, the application
wants to continue using the indexes for both query and w
