Not that much I have about 30THs. Been watching the block % under my workers. It's seemed to freeze for pass 5 hours. Shares are still getting accepted like crazy though??
It feels like forever the first blocks! Now I've been through this a couple of times, each new miner I've pointed to kano had a 30+ hour wait before second block so I think it's evil. However it equals out when payments start getting high and equilibrium when they come fast too.
