My reported pool speed is about half what my speed on the miner and awesome miner report.

I've tried it on a couple of pools and they seem to report the same reduced speed. 2x1080ti hashing at 145mh/s as per report in mining window and awesome miner, yet in the pool window it shows a fairly constant 80mh/s.

I left it 24 hours and it didn't change, so I switched pool and within 10 minutes it's constant 80 again, yet still showing 145 at my end with no rejects etc, any ideas what am I missing here?
