It will take forever on large databases, but for replicated databases a
phased reindex /could/ come in handy. I know at my site (a university)
we do crazy bulk loads once a year (incoming freshman) and performance
isn't so snappy until after a reindex. It might be my tunings, but with
the re-index everything goes fine so my thinking is it is a few
fragmented indexes....
I'd suspect there's something else going on. BTW, I worked at Stanford
University for many years maintaining their directory servers, and while
proper indices are definitely a must, re-indexing was only necessary when
changing them. Otherwise, performance was spectacular. Properly tuning
OpenLDAP is always a must. ;)
Note that prior to OpenLDAP 2.4, indices are not truncated when slapindex
is run. OpenLDAP 2.4 adds the -t option to truncate the existing indices
out of the database, which is also handy. ;)
