Hello Thierry, sorry for my short reply, i am not in the office this week. I can confirm that all my test run several times, the first run is always slower because of the empty cache. The mentioned results are all average values without first run. The problem occured on all tested 2.x versions. I found it on 2.0.17 but can also observe it also on newest 2.3.2. Next week I can send you the dse.ldif for analysis.

The search returns ~500 groups. The first lookup of those groups is significantly longer because of entry cache priming. Could you confirm that if you do twice the same search (1.4 and 2.x), the second search in 1.4 is much faster that the second search on 2.x ? best regards thierry On 3/16/23 09:38, Claas Vieler wrote: Hello William I cant see any difference expect duration best regards Claas 389-Directory/2.3.2 B2023.073.0958 [16/Mar/2023:08:24:51.321404978 +0100] conn=51 fd=66 slot=66 connection from local to /run/slapd-389ds.socket [16/Mar/2023:08:24:51.323985845 +0100] conn=51 AUTOBIND dn="cn=root" [16/Mar/2023:08:24:51.325995690 +0100] conn=51 op=0 BIND dn="cn=root" method=sasl version=3 mech=EXTERNAL [16/Mar/2023:08:24:51.328098136 +0100] conn=51 op=0 RESULT err=0 tag=97 nentries=0 wtime=0.000082030 optime=0.004197632 etime=0.004276581 dn="cn=root" [16/Mar/2023:08:24:51.328272655 +0100] conn=51 op=1 SRCH base="dc=example,dc=com" scope=2 filter="(uniqueMember=cn=testuser1,ou=People,dc=example,dc=com)" attrs="distinguishedName" [16/Mar/2023:08:24:52.285988416 +0100] conn=51 op=1 RESULT err=0 tag=101 nentries=532 wtime=0.000077055 optime=0.957714945 etime=0.957784949 [16/Mar/2023:08:24:52.286275743 +0100] conn=51 op=2 UNBIND [16/Mar/2023:08:24:52.291936625 +0100] conn=51 op=2 fd=66 Disconnect - Cleanly Closed Connection - U1 389-Directory/1.4.4.19 B2022.313.1200 [16/Mar/2023:09:10:20.353075132 +0100] conn=101 fd=64 slot=64 connection from local to /var/lib/dirsrv/slapd-389ds/slapd-389ds.socket [16/Mar/2023:09:10:20.355714488 +0100] conn=101 AUTOBIND dn="cn=root" [16/Mar/2023:09:10:20.357681511 +0100] conn=101 op=0 BIND dn="cn=root" method=sasl version=3 mech=EXTERNAL [16/Mar/2023:09:10:20.359700165 +0100] conn=101 op=0 RESULT err=0 tag=97 nentries=0 wtime=0.000036305 optime=0.004064382 etime=0.004098191 dn="cn=root" [16/Mar/2023:09:10:20.359896870 +0100] conn=101 op=1 SRCH base="dc=example,dc=com" scope=2 filter="(uniqueMember=cn=testuser1,ou=People,dc=example,dc=com)" attrs="distinguishedName" [16/Mar/2023:09:10:20.367652447 +0100] conn=101 op=1 RESULT err=0 tag=101 nentries=532 wtime=0.000077477 optime=0.007755733 etime=0.007830994 [16/Mar/2023:09:10:20.369055287 +0100] conn=101 op=2 UNBIND [16/Mar/2023:09:10:20.371940374 +0100] conn=101 op=2 fd=64 closed error - U1 Gesendet: Mittwoch, 15.
