Tcl + C is a time-tested solution that works quite well for a variety
of things. I think mod_dtcl is actually a good example of the power
of Tcl's C API.

Yep...

tcl.apache.org gets about 2000 hits a day, now, and has been running
unattended in my month of absence.

Depends on a lot of factors.... CGI's have to fork new processes, so
dtcl is conceivably faster. Depends on how much processing the C code
does.
You might write it as a CGI first, and then when the bugs are ironed
out, create a Tcl wrapper.
Good luck,
