Hi all:

We had to reindexing/refragmenting the database because searchs by trailing date not working.
The new documents was not indexed by date. After reindexing (the operation takes 40 hours), all works fine. However, searchs by text that previously took less than a second, now takes between five and ten seconds. Also, database size increased 30 GB.

The database has 12,5 millions documents and 140 GB in two forests. Run on hp DL385 AMD 64bits Quad Core 2,2 Ghz, 16 GB RAM and one disk 250 GB raid 1 on EVA8000. The operating system is Windows 2003 Standard Edition SP2 and MarkLogic Server 3.2.

We modified parameters database for improving performance, now Marklogic process in memory is 12 GB (before 9,5GB), with not sucess.
                                Before    After
in memory limit                 524288    1048576
in memory list size             1024      1024 (máx.)
in memory tree size             256       1024
in memory range index size      16        64 (máx.)


We hope to improve the performance without to buy new hardware and licens.

Thanks and regards,
