Hi list, My problem is solved. Since I changed my SCSI to a Quantum, I haven't have more problem with performance. I recompiled the pwd_mkdb.c program using more RAM memory and the performance became better. Before compilation the "delete user" operation takes 3 minutes, and now the same operation takes 11 seconds (whe have about 12000 usernames - thanks Pedro Vazquez ;).
