The idea of plain text files appealed to me a lot (I had been pondering
something similar myself, but couldn't have implemented in such a
general fashion), so I decided to try it in my Usenet news statistics
script, on which I'm learning lots of Ruby techniques.

So for a start, I plugged KirbyBase in just as a cache - where before, I
was reading header data from a news server each time, in the new version
I save the raw data to a KirbyBase, add only recent messages, then read
the part of the data I want (by date) from the KirbyBase.

Unfortunately, it turned out to be none faster. I wonder if I'm doing
anything wrong. What I save in time waiting for the server, KirbyBase
seems to eat away in processing time (disk access hardly mentionable
with my 6000 rows, 10KB of data). Is it true that you need a lot of
processing power to use it, and my PIII-500 (Win-2K/Cygwin) is just not
up to the task?

You said:

and even

Well, one reason to try it was that I had installation problems with
SQLite, so I can't compare directly, but now I wonder how it could ever
compete. One select for string equality on my 6000 rows takes half a
second or so, so I gave up on that completely.
