Hi @ll, I have an OpenLDAP 2.4.21 on a Ubuntu Server 10.04. The server is used for auth, when I have more than 20 user logged the server reponds very slow and has hight load. I have my config in this way: for 60000 registers in my db olcDbCheckpoint: 1024 5 olcDbCacheSize: 180000 olcDbConfig: {0}set_cachesize 0 94371840 0 olcDbConfig: {1}set_lk_max_objects 4500 olcDbConfig: {2}set_lk_max_locks 4500 olcDbConfig: {3}set_lk_max_lockers 4500 olcDbIDLcacheSize: 540000 The server is part of a multi master squema (MMR). Where I can found a good documentation for tunning my server in this scenario? Regards. -- Luis Antonio Galindo Castro aka FunkyM0nk3y Fingerprint: 237E EFE1 6055 BCEB ACD0 7A49 30FC A883 0044 A85E
