I've had two different kinds of customer requests for jumbo frames
- customers that want very large frames for performance reasons;
Many ethernet switches support 9000 or more, some don't,
and some technologies like ATM support ~4470.
Sometimes the ability to provide them depends on tunnel modes.
- customers that want frames that are at least ~1700-1800 bytes
so that a few layers of IPSEC or VLAN headers or whatever
won't break the 1500-byte packets inside them.
Note that this isn't my regular email account - It's still experimental so far.
And Google probably logs and indexes everything you send it.
