Re: Data queue to web app

Actually, the fastest throughput you can get is if your frame size is
the same as the receiving and/or sending frame size all the way
through the wire.

Usually you would set your frame size to the frame size of your
ISP's router if going through the internet, otherwise I think you
just want your frame size all the same on a network.

If you have your transmitting frame size higher than the receiving
frame size there is a lot of juggling that takes place chopping the
frame up into the size of the recipient.  If your transmitting frame
size is lower than the receiving frame size you are just not putting
through as much as you could be.

I have seen 596 or so used quite a bit for dial up ISP's, I am not
sure what ISP's routers normally use, nor local network.

The drawback of large frame sizes is in error correction.  If you send
a large frame size, of say 1496 and everything is set for 1496 everything
will be fine, unless there are errors on the line.  Then the whole packet
of 1496 bytes has to be sent.  So I guess a larger frame size if usable is
good for clean connections, but on noisier connections you would want
to reduce your frame size.
