Thank you, that is interesting. Doesn't it also imply is that with the
smaller MTU of 590 you'll end up having
fragmentation which will add a little bit of processing overhead? I
understand it is not that big of a deal since
fragmentation happens a lot, but for the best performance yes, both sides
have to agree on a decent MTU.
In TCP, both sides do agree. That is the negotiated MTU.
Of course, larger MTUs have better transfer rates. That is the old
performance vs. size trade-off. If so configured, both end points
should use the configured MTU of the network. However, they should also
work with limited devices with smaller MTUs.
