OL 2.3.18 syncrepl vs slurpd
I'm attempting to convert from using slurpd to using syncrepl.
However, my testing is developing a definite belief that syncrepl is
hopelessly unable to keep up.
I have a test situation where I have loaded a 48,819 entry ldif using
slapadd -q -w on the master and slapadd -q on the replica. I then
proceed to perform 12,654 modrdns, 56 modifies, and 961 delete/add
actions in rapid succession.
Using slurpd, the script runs in 28 minutes on the master and within
one (1) minute the replica is up to date. Using syncrepl, the script
runs in 25 minutes on the master, but the replica will take about 45
minutes to get in sync (one test took over 90 minutes).
I haven't found any syncrepl tuning documents, so I'm kind of
shooting blind after reading the Admin Guide and the syncrepl man pages.
I'm using the following in the master slapd.conf:
syncprov-checkpoint 1000 10
I'm using the following in the replica slapd.conf:
Doing ldapsearch calls at sixty second intervals, it appears that
syncrepl is handling approximately 200 updates per minute.
Anyone have any insight to what I've done wrong or where I should
