If I'm not mistaken that's with jumbo frames enabled. Consumer NICs
typically do not support jumbo frames. Regardless, if you're getting
~2.5 times my throughput estimate then your MythTV usage is consuming
about 2% of your available bandwidth instead of my 5% estimate, so
instead of wasting 95% of the network bandwidth by not using it you're
wasting 98% of it.

If you were doing video editing then that would be a different story.
This is large(ish) scale bulk data transfers where high sustained
throughput is necessary. But then, you would do this kind of wiring in a
studio environment, not the entire residence.

So, yeah, whole-home wiring just doesn't make sense.
