Weirdly no one had done it so far. That's the reason why I cooked up some high level devices :)

It it's not the file paradigm, it has to be system calls (plenty of them) set in stone, which could quickly turn into a problem or you probably mean a wrapper library?

The one point I keep driving is Kubernetes does so much useful stuff that is a pain to manage otherwise, that it's totally worth the risk currently posed by its rough edges. I'm hoping that came out clear in the article.

While already available tools should have sufficed and PSI should be good for it, a very important capability that PSI provides system administrators is its high-resolution. Using PSI, with specialized tooling, system administrators can aut

kees99, you should check the "total" fields. They have information in microsecond resolution.

Thanks for sharing this. This is such a great resource.

I've never really done any serious work on anything other than Linux. But I always wanted to try out kqueue(). Even if I don't add a separate section on kqueue(), I think it warrants a clear mention.

OK, noted. Thanks for sharing.

That should be pretty trivial to implement with getrusage() http://man7.org/linux/man-pages/man2/getrusage.2.html

OpenBSD and FreeBSD do have sendfile(), but args are different compared to the interface presented by Linux. It should be trivial to write a wrapper, though: https://man.openbsd.org/FreeBSD-11.1/sendfile.2 https:&#x2F

String handling in C is such a PITA. Especially if you're used to languages like Python.

LOL! Thanks :)

Yes, IIRC, even Nginx uses the general structure you're describing.

(Glances at the "Programming Rust" book which has been sitting on his desk for months and thinks about writing an indemnification clause in the LICENSE file)

Points well taken, marios. Will try and fix strcpy(). Should certainly mention kqueue(), too. Will fix. Thanks.

As mentioned in the first part of the series, the main idea is to compare and contrast Linux server architectures. ZeroHTTPd doesn't implement the HTTP protocol in full and you can easily crash it because of the way it uses memory buff

Would be lovely to get my hands on such metal :) I wonder how Linux thread scheduling scales on multi-CPU machines. To keep things simple, I specifically chose to go with a single-core machine to benchmark all architectures.

Oh, wow. Never knew about this. This is most certainly worth checking out.

Unfortunately, the current POSIX AIO implementation is done in user space by glibc. That's the reason why I covered poll and epoll. The next logical variant to add would be io_uring.

by shuss 7y ago
Will certainly need to add that! :)
