I've got a bunch of root servers with i7-2600k CPUs which come with free electricity. I want to let them run some zcash miner, just for the sake of fun. I know, the hashrate can not be compared to GPUs anymore, but still a few more Sol/s is nice.
I was browsing the forums and Google for a while now, but I can't find any good details on CPU miners.
Which ones are available right now that perform quite good?
My servers are running on Linux btw.
