This is on my T21 thinkpad (850Mhz pIII) with 2.4.5 kernel and cvs
guile:

address@hidden:~/src/net-http$ time guile -c '(use-modules (net http))
(display "X")'
X
real    0m0.307s
user    0m0.270s
sys     0m0.030s
address@hidden:~/src/net-http$ time guile -c '(use-modules (net http))
(display "X")'
X
real    0m0.308s
user    0m0.300s
sys     0m0.000s
address@hidden:~/src/net-http$ time guile -c '(use-modules (net http))
(display "X")'
X
real    0m0.310s
user    0m0.280s
sys     0m0.020s

The machines are very different, but not enough to account for a greater
than 10 speed improvement.

The new guile is fast even without all the fancy compilers and jit code
generation.

Give the cvs guile a try.
