VERY poor download speeds.

Ok, so fresh install of 2.1 x64.

Just had 80/20 Fiber installed.

Modem is synced with exchange at 76.07mb down.
With modem directly attached to pc, I get similar speeds.

However once connected to pfsense, with WAN in PPPoE, throughput drops to ~5mb download, but it still managed 17mbit up.

MTU is set to 1458, as advised by my ISP.

pfsense machine is:
Intel(R) Pentium(R) Dual CPU E2140 @ 1.60GHz
2Gb DDR2 Ram
64Gb SSD

Any ideas why performance is so bad?

It should be noted that I had similar poor performance from my old 1.2.3 machine, which I put down to a combination of being a very old pfsense version, and a celeron processor.
I was expecting these issues to disappear once replaced with (what in my opinion is) a total overkill specced machine, and a fresh install.

Well this issue has magically fixed itself, no idea why :S
