I realize this may have been answered in a different post, but the thread is 100+ pages, so if someone (especially nicehash) has already answered, please forgive me.
So the question is this - why does the NH pool request work restarts so often? Even when I'm hashing the same order (I know for sure because there was only one active one and all miners on the pool were assigned to it), the pool requests work restart every 10 seconds or so. This has dramatic effect on the average hash rate. For example I have a really stable 3.5 TH on regular pools, but on NH with all the work restart requests, it drops down to 2.9-3.1. So this actually means that any increase in pay-per-GH over a regular pool will be negated by the significant decrease in your rig speed.
Couldn't it be adjusted so that there is no work restarts unless you change the order you are hashing for, or something similar? See the screenshots, work restarts 10-12 seconds apart.
