Is there any modern review of solutions to the 10000 client/sec problem

Question

(Commonly called the C10K problem)

Is there a more contemporary review of solutions to the c10k problem (Last updated: 2 Sept 2006), specifically focused on Linux (epoll, signalfd, eventfd, timerfd..) and libraries like libev or libevent?

Something that discusses all the solved and still unsolved issues on a modern Linux server?

Answer 1

The C10K problem generally assumes you're trying to optimize a single server, but as your referenced article points out "hardware is no longer the bottleneck". Therefore, the first step to take is to make sure it isn't easiest and cheapest to just throw more hardware in the mix.

If we've got a $500 box serving X clients per second, it's a lot more efficient to just buy another $500 box to double our throughput instead of letting an employee gobble up who knows how many hours and dollars trying to figure out how squeeze more out of the original box. Of course, that's assuming our app is multi-server friendly, that we know how to load balance, etc, etc...

Answer 2

Coincidentally, just a few days ago, Programming Reddit or maybe Hacker News mentioned this piece:

Thousands of Threads and Blocking IO

In the early days of Java, my C programming friends laughed at me for doing socket IO with blocking threads; at the time, there was no alternative. These days, with plentiful memory and processors it appears to be a viable strategy.

The article is dated 2008, so it pulls your horizon up by a couple of years.
