Howard gave me a general rule of thumb:
For BDB, idlcachesize should be equal to cachesize in slapd.conf
For HDB, idlcachesize should be 3 times cachesize in slapd.conf.
Howard, why the difference?
I touched on this in a previous reply. back-hdb manages its DN info
differently than back-bdb; in simple terms, it uses a large number of
small IDLs while back-bdb uses a smaller number of large IDLs.
Do the internal cache structures get slower with size?
Not appreciably. They're AVL trees, so they stay pretty efficient as the
number of cache items grows.
