Re: slapadd performance problem in solaris
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.
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is being withdrawn from distribution for .25.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.)
We are testing openldap 2.2.20 recently. We have met serveral problems.
slapadd's performance is not linear with the count of entry in solaris.
under solaris,at the begging of load,size of data file increase quickly,but subsequently load slowly and slowly.And I found,slapd
is always in sleep stat.but it isn't happen when loading 10k data. BTW,suse linux have no such problem.
