Hi, I'm just testing performance of db-4.5.20 vs. db-4.8.26 and found that db-4.8.26 much slower than db-4.5.20.
BerkeleyDB: 4.5.20 real 0m4.973s user 0m2.043s sys 0m0.784s
BerkeleyDB: 4.8.26 real 0m7.461s user 0m2.517s sys 0m0.995s
The OS is openSuSE-11.1, I just built openldap-2.4.21 twice, using the same slapd.conf to setup two servers and slapadded some 30,000 dummy entries, the search was done on a subtree with 10,000 dummy entries. The script can be found here: http://pastebin.de/4428
In fact I tested filesystem performance as well, creating partions with ext3, ext4 and btrfs, but fould that these filesystems had almost no influence on performance, at least not with such a small database.

I forgot the numbers for ldapdelete:
BerkeleyDB: 4.5.20 real 0m4.973s user 0m2.043s sys 0m0.784s
deletes: ~10.000 real 13m9.496s user 0m0.723s sys 0m0.528s
BerkeleyDB: 4.8.26 real 0m7.461s user 0m2.517s sys 0m0.995s
deletes: ~10.000 real 16m52.525s user 0m1.699s sys 0m0.725s

Is there any advantage in building with db-4.8.26?

On Solaris we've run into deadlocks with db-4.7.25 that were fixed by switching to db-4.8. Haven't seen the same situation on Linux.

I ran into deadlocks on Debian and db-4.8.26 on heavy write operations.

Hello all,
I would like to know if an early version of openLdap (futur 2.5?) is already available with support of LDAP transaction mecanism ( draft-zeilenga-ldap-txn-15.txt) Even a non finalized development version may be ok for me.
Thanks in advance for your help, Regards, hptf
