Looks alright, "Stratum requested work restart" means your miner got new work from the server. The difficulty at these pools is rather high and can't be adjusted, so it might take 30 minutes or so to find a share. What cooling do you have? I found that I get 80h/s with only 4 cores, same as with 8 cores due to overheating. Really need to put some big heatsink on the CPU.
