That is very very strange. The code is, as you would expect, the same
for all platforms.

Something I think is very interesting is that the in argument test is
faster on Linux than Windows, so it's not as simple as the marshalling
just taking a long time. The only similar thing I've seen is a problem
that only affects the TCP loopback on Linux, where the time for a
transfer fluctuates enormously with different sequence sizes. See

But I don't think that's anything to do with the problem here, since
you say the same problem occurs over the network.

If the benchmark code available?  If so, where can I get it?

Cheers,

Duncan.
