I agree, but "high enough" is apparently just 60%. The standing question is, what's the actual level in different kinds of servers?
In other words, I've given a metsric, ATR at 60% is the break even point for poll vs. epoll. So far the only responses I've got haven't even tried to give out a metric, let alone say what their actual ATR is but they claim that it's low.
I'm a scientist, so in the same way I don't believe my own research, I don't believe their rhetoric.
