 Do you know where your variables are?  Comment on   I'm curious
what you mean by "DBD::SQLite is not a sound database". I know
it's a single file, lightweight, minimal-SQL set database, but
to me something that isn't sound is buggy. Is that what you're
saying? Just curious. (By the way, I just discovered a GPF-
producing bug if I switch my code to use selectrow_array() with
a pre-prepared statement on Win32, so maybe you've got a point.
;)  And yes, I fully expected the database solution to be much
slower than the in-memory hash solution. I mentioned that in my
post. I was attempting to quantify how much slower, and how
sensitive the database version is to dataset-size.  Wrapping in
transactions definately helps. Take the example of my building
the database initially. With transactions, it takes the blink of
an eye, but without, it takes about 45 seconds to build the
database on my system. But on the query side, I'm specifically
trying to engage in single queries, and didn't want to see
transactions influenci
