Thanks,

We will undo changes to in-memory tree size and in-memory range index.
Also, will migrate as soon as posible. Do you recomended MarkLogic 5 (just 
released) or 4?

Asunto: Re: [MarkLogic Dev General] Decreased performance afterreindexing       
database in MarkLogic 3.2
 
I can make a couple of observations that are valid for every version of 
MarkLogic Server to date:

* The changes to in-memory tree size and in-memory range index size were not a 
good idea. Higher limits mean larger in-memory stands, which will increase 
memory utilization. That is not likely to improve performance, and may well 
hurt performance. I would undo those changes.

* The increased database size and memory utilization probably indicate a large 
number of deleted fragments, which should be visible on the database status 
page. Merge the database to get rid of those.

3.2 is indeed very old now, and I would recommend upgrading as quickly as is 
practical. Note that upgrading will require more reindexing. So I would defer 
the full merge, recommended above, until after that upgrade is complete.
