HI there ppl, I have quite afew systems here with ~10.00 accounts on ea ... and pwd_mkdb is _very slow now ... Takes 2+ minutes to rebuild the damn databases every time. I'm not concerned with passwd command , even though as I understand it doesn;t do one-point update so far and rebuilds everything from a scratch, but I'm trying to somehow speed up the pwd_mkdb itself. So they're a few ways I can see looking at the source code . For example it does two passes on a master password file it's fed as a parameter - once for unsecure and once for secure databases - so this could be made only once and we can write in to db's in parallel, Secondly may be I'll be able to reuse at least parts of the structure used for db->put for secure and usecure db's. And aslo - does any of programs actually use pwd info indexed by line number ? Do we really need this pass ( there're actually two passes) ? I want to check the the thing using profiler , just to see what eats most time in the program ( I do have a feeling already that it's all those dp->put's ). Rashid.
