41 seconds to open a directory...

Question

We are about to run a Pilot Project and are experiencing very long response times.
We have loaded 111,175 Files under 12,372 Directories for a total of 6.55 GB.
The directory structure is:
/HOME/MDDM
/A, /B, ...etc for the 25 letters of the alphabet
/A/Andrew
/A/Armstrong ... etc 1 folder per person
and under each person there are 4 subfolders.
Opening /MDDM takes 14 secs (only 1 user connected, using FTP)
Opening /MDDM/A takes 41 seconds! (it contains 106 "names" subfolders).
We are running Oracle 9i DBMS and 9iFS off a single 1.6GHz Pentium CPU under Windows 2000 (Oracle text is turned off for now but will be activated later).
It also appears that it is directory navigation/creation that takes such a long time (it takes 20+ seconds to create a new directory).
- Is there a way to optimize directory handling?
- If we are stretching the server, what type of configuration should we look at ? We want to start with 15 users (and will hugely scale to tens of thousands of users if successfull).
Thanks,
Benoit Chenette

Hi Benoit.
To determine what the issues are will require isolating the problem to the database or to iFS, and then examining each in further detail.
The best way to proceed is to contact your Oracle Support representative, and ask for their assistance.
Oracle Support can engage our internal performance experts if they need further assistance.
Hope that helps.
