MathLink Transfer speed

Hi All,

I made a small web site which measure the MathLink transfer speed. It
uses
a simple installable MathLink program to measure the transfer speed.

<http://goriate.melt.kyutech.ac.jp/~miyaji/index-e.shtml>

Here are the selected results of transferring 100000 integer list;

PII(600Mhz) Linux(Pipe) 0.023sec
PowerMac G4(400MHz) MacOS9(PPC) 0.39sec
AMD K6(400MHz) Windows98(FileMap) 2.75sec

Interestingly there are more than 10 times differences between protocols
and machines.
I hope these results will help you to guess how long does your program
take
to transfer the data.

It is not difficult to measure the transfer time on your environement.
There are executable programs for Mac, Windows, and Linux.
Or if you need to compile for your environment, you can download the
source code.

Also I'm very glad to get more data for the various platforms.
