I've also used dbi:CSV before and it is way cool. I think stevieb's comments are completely right and that this will solve your problem.

At some point, you may find that the CSV DB doesn't fit your needs in terms of features or performance. If that happens, I would recommend SQLite. And also check out SQlite Manager for Firefox. SQLite does a lot of what MySQL can do but without the admin hassle. In a multi-process environment, SQLite requires that an exclusive lock be acquired to update the dB for a write. So performance is not the same for writes, but for reads, this thing works fantastic! For complex operations, I found that you can dynamically vary the amount of memory that SQLite uses. That kind of fine tuning can have a big performance impact.

Update: The reason that SQLite is so cool is that it uses a simple file for its work (rough comparison to DBD CSV) So it does not require a server to be running (along with the admin hassles with that).
