Can you post the code you are testing the timing with?

Marshalling (out) is very slow if marshalling to a string; the solution is
to marshal directly to an IO object, i.e.

   Marshal.dump(myobj, $defout)

is much faster for large dumps than Marshal to a string and then writing the
string.

Marshalling in seems to be very fast indeed.
