There are performance issues when you go to the secondary blocks for the
index, but even on this 386/40 it is not that bad.

Well, that helps quite a bit.  I only have about 3300 messages, it is just
the message numbers that are getting up there.

This PC has been running virtually non-stop for 24/7 with Binkley and a
couple different message readers since November 1992 (used one until Y2K,
then had to change as it was not compliant). I added a hard drive and some
memory 7 or 8 years ago.  I am often out of town for a week or more at a
time, and it just keeps picking up the mail.  The whole family has been
away as long as 21 days at a time, and it just keeps picking up the mail. 
I do tend to re-boot every few months when I do a cleanup of the message
bases and a defrag of the drive, but have gone as long as 6 months.  I
usually shut down over Christmas holidays and clean out the dust and cat
hair.

I like reliability.  :-)

 PK> Regardless of File system and memmory availability, I am pretty

I guess that I will not worry too much about it.  :-)
