Re: slapadd performance problem in solaris

[Howard Chu <hyc@symas.com>]

Your DB_CONFIG file is inadequate.

In general, we also see slower performance on Solaris than Linux, even 
when properly tuned. But you're not there yet.
http://www.openldap.org/faq/data/cache/1075.html

Also, since you have just recently begun using the package, you ought to 
use the most recent available. 2.2.23 or .24 would be better (although 
.24 added a new feature in libldap that causes it to crash, this feature 
is being withdrawn from distribution for .25. See ITS#3612. It would be 
safe to use the 2.2.23 libldap until .25 is released; the .24 slapd is 
not affected by the bug.)
