SQL Databases like SQLite aren't slow.
After applying a patch, I can do a complete "show-diff" on the kernel tree
to see the effect of it in about 0.15 seconds.
Also, I can use rsync to efficiently replicate my database without having
to re-send the whole crap - it only needs to send the new stuff.
You do that with an sql database, and I'll be impressed.

Ok, but if you want to search for information in such big text files it
slow, because you do linear search -- most datases use faster search
algorithms like hashing and if you have multiple files (I don't if
you're system uses multiple files (like bitkeeper) or not) which need a
system call to be opened this will be very slow, because system calls
itself are slow. And using rsync is also possible because most databases
store their information as plain text with meta information.
