hi,

great work richard, i hope to try this= soon. the network performance is the biggest draw for me.
<= /span>
do you any feeling why plan9 sees only 200Mbps ether?=

is it the stack design, how plan9 accesses the ha= rdware? or maybe the 300Mbps quoted is only when using jumbo frames?<= br>

Ethernet bandwid= th for the 3B+ on linux is claimed to be

just over 200Mbit/s.=  Not gigabit, but still it's a 2x
