Compared to Perl, it is.

Yup, no doubt about this. The glue between sqlite for example could be
optimized much more. Keep also in mind that most of the wrapper code for
all this is written in Scheme, not C.

Hey, 10 secs vs. 5 secs is actually pretty good!

Indeed, there are worlds between them. But that is to be expected,
since Perl is an I/O and regexp engine.

Chicken will never be in the same ballpark as Perl for these kind of
things.

But, boy, try to compute the ackermann function in perl! ;-)
