Is the HN hug of death truly only single digit QPS?
Assuming:
* 1 page/visit, which is the modal value based on my analytics
* the period where it is on the front page is 6 hours (I don't know this, but I could if I could be bothered to go back and look; I don't have granularity down to the minute, though)
That is 20000 requests/(66060), which rounds to 1 request/second.
Of course, there are all the other assets (JS, images, etc) that you need to account for as well. And it might spike to higher.
I think it’s more likely that there’s a big flood at first and then it drops off towards a low number.
