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.

test result:
solaris suse linux
1k 5seconds 10k 45seconds 100k 780seconds 156 second
1000k 15hours 2031 second

By the way, in OpenLDAP 2.3 the "slapadd -q" option is several times faster.
