Re: [MacPerl] DB_File File Size

[Fred Giorgi <fgiorg@atl.com>]

Did you ever get a satisfactory response?
I did some research within the berkley db documentation. See my post Re:
DBM files get big and slow. Mess with the HASHINFO structure and watch the
file size change. It is very controllable on my 6100. If not explicitly set
the HASHINFO structure is supposedly set wiht  defaults and according to
the native OS. So I'd like to hear how you can control your system.
If you are not familiar with viewing files as hex I do it with an plug in
to BBEDITLite called hex dump.
