FreeBSD doesn't enable polling by default. You can turn it on for many
nics including sis if your kernel supports polling (which isn't
default in GENERIC, correct me if I'm wrong):

ifconfig sis0 polling

Performance depends on your network usage. I've not seen any
improvement with polling enabled on a net4801 as it generally is to
weak for high throughput.
