As a side comment, we have already documented that about 1 million entries is
the practical limit for slapd on a 32 bit machine. Since 64 bit machines are
so common today, making slapd perform well on a 32 bit machine is no longer a
priority.
Also, by design, tcmalloc doesn't release freed memory back to the OS, since
it will most likely be needed again. It's normal for the slapd process size to
never shrink.
One thing you can check is to add a "database monitor" to your slapd
configuration; one of the entries under cn=monitor will report the number of
items in the back-bdb cache. Please provide this information here.
