not sure what it is, but TRC-p2pool is currently at ~2.2GH/s.
The problem is, that the total-network-hashrate is quite low,
so when a few ASIC-owners join, they push the difficulty into limits that the rest of the network can not handle once the ASICs leave.
And that's exactly what's happening the last couple of days, when the difficulty is low, ASICs join and push it high up to the sky, then leave and remaining miners need hours and hours to create a single block (and probably also leave because it's not profitable anymore).
