compared to other pools the reject rate on wafflepool is usually lower less than 4% on my setup
Reject rate over a short time isn't useful, and overall the pool averages ~3%. Varies a huge amount though, some 1-5min periods are 0%, some are 20%, the difference is, when you're mining a coin at 20% stale rate, we expect a huge profit from those coins (making the 20% worth it). This is expected, and accounted for in the switcher.
Pool is down tried US west server as well.
