RE: [MarkLogic Dev General] Decreased performance afterreindexing database
in MarkLogic 3.2

Hi Mariano,



I believe the recommended route for such an upgrade would be to upgrade to
the latest version within the 3.2 branch first, upgrade from there to the
latest within the 4.0 branch, upgrade to 4.1, upgrade to 4.2, and then
upgrade to 5.0. Obviously start off with a backup of your original 3.2
installation..



Kind regards,

Geert

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.
