There is a reason it's called cryptonight heavy. If you are only losing 33% be glad. MY quad Opteron servers went from over 2100H/s to under 900! Almost a 60% loss!
It's not "losing" as its a different algorithim and everyone on the network is using the same one
Just because an algorithim gives you 1 million hashes is irrelevant since everyone else would have 1 million too if you get my point.In saying that CPUs were hit harder than GPUs due to the increase of memory usage in the algorithim.
It's "losing" when device A got B and device X got Y. When the ratio between B and Y is not equal, it's a loss is it not? CPUs have become less efficient and have LOST to GPUs even more so than they already had with the new algo in place.
Also, the auto config for CPU is no longer optimal in xmr-stak, at least not for quad Opterons. It will get me 500H/s and my old config does ~900H/s. I will try to hand tune to see if there is any other gains to me made.
