Re: slapadd performance
We are using Symas OpenLDAP 18.104.22.168 on a Red Hat EL 5.2 64-bit with 8GB of memory.
My DB_CONFIG settings are:
set_cachesize 3 0 2The 10 million user load finished in about 18 hours. I believe the primary issue is the fact that we have a single disk on the system. I assume that if I were to move the database and log files off to separate disks I would get much better performance.

What are the settings in your DB_CONFIG file? It is absolutely critical to the performance of slapadd. What version of OpenLDAP are you using? What version of BDB? What operating system?

I am trying to perform some benchmarking against OpenLDAP. So far I have
ran my tests against a 100K and 1Million entry database and I have had
rather decent numbers. My final set of tests were to be ran against a
10Million entry database. Unfortunately, I am having difficult loading
the database with this many entries. I have generated 10 1Million LDIF
files. I am using "slapadd -c -q -v -l <file>" to import each file. The
first 2 files took approximately 15 minutes each to load. The remaining 8
files are taking progressively longer and longer. So much longer that I
anticipate the entire proceess to take well over 24 hours. My question is
is there anything I can do to increase the performance of slapadd. I
assume that since slapd is not running at this point that the normal
DB_CONFIG and slapd.conf settings do not have much affect.
