No business or web site which has 10K concurrent users will be using just one server. Scalability beyond 10K users/server doesn't buy you anything.

- jshen 15y agosurely you jest
- peter_lawrey 15y agoIn your experience, have you ever seen or heard of a business or web site with more than 10K concurrent users who thought it was a good idea to place all those users on just one server?
- jshen 15y agoconnections and users are not the same thing. Accomplishing a task with fewer resources is better, so when you say " Scalability beyond 10K users/server doesn't buy you anything", you are wrong. Imagine if you have a giant datacenter like google, and heat and power are a serious problem. Accomplishing a task with fewer servers is a serious win.
- jshen 15y agosorry, that quote wasn't from you, but I think the two of you are making the same point, which I disagree with.
- peter_lawrey 15y agoFrom a search I did suggest that Google have nowhere near 10K users per server. That is likely to be because the servers spend most of their time performing searches. The overhead of managing persistent connection is likely to be a small portion of what they do, like most real applications.
- jshen 15y agoYou seem to be implying that since, in this one use case, it's not useful, then it's not useful at all. That's a non sequitur. I already gave one concrete example of where it was useful in my past experiences.
- peter_lawrey 15y agoFair point.
