Antw: dynlist performance

Hello, I'm testing the dynlist overlay on OpenLDAP 2.4.38 because i have a static group of around 10K uniqueMember. I want to have now a equivalent group with

dynlist. I have configured my overlay dynlist like this : dn: olcOverlay={2}dynlist,olcDatabase={1}bdb,cn=config objectClass: olcOverlayConfig objectClass: olcDynamicList olcOverlay: {2}dynlist olcDlAttrSet: {0}groupOfURLs memberURL uniqueMember And my group is quite like OpenLDAP example in documentation : dn: cn=GeneralisationDyn,ou=Groups,dc=example,dc=com objectClass: top objectClass: groupOfURLs cn: GeneralisationDyn memberURL: ldap:///ou=People,dc=example,dc=com??one?(objectClass=person) uniqueMember: uid=user1,ou=People,dc=example,dc=com uniqueMember: uid=user2,ou=People,dc=example,dc=com [...] My backend is Berkeley DB and i have tune it in order to have quite fast responses on searches, and locally on my server (virtualized with a single proc), it take that time to return the entries found by memberURL : real 0m0.272s user 0m0.040s sys 0m0.023s

If i run an ldapsearch to see all uniqueMember of my dynamic group it take around 8 to 10 seconds to have the output ! Why a so big difference of response time in a search of entries and a search

of uniqueMember inside a dynamic group ? Is there some tuning for dynlist plugin ? Notice also that when i search uniqueMember inside my static group with quite same number of uniqueMember) i have less than 0.1 seconds of real
