Expecially big fat dumb packages like the HTTP library. B-)

There's been very little tuning on the HTTP library. I think the newer
version 0.3.1 (check here:
        
        http://evan.prodromou.san-francisco.ca.us/software/net-http/

) should be a bit quicker, but I don't have any numbers on it.

(Sadly, I mislaid my pwd for the GLUG project thingy for (net http),
and I haven't updated the projects list. I guess I should dig it up
and do so...)

    NWVD> Will any startup speed improvements make it into 1.6?

There are, I think, 3 current technologies on the board for improving
speed:

        * guile-vm: compile Guile to a bytecode and execute the
          bytecode

        * guile-lightning: use GNU Lightning to do a "Guile JIT
          interpreter" 

        * hobbit: compile Guile code to C, compile the C, and run it. 

I don't have -any- idea how well any of these things work with
GOOPS. My first guess would be: crappy. B-)

Out of curiosity, what context are you using (net http) in, that
startup time is important?
