Multi-threading in Linux and Windows

"In Linux everything is bad regarding multithreading"

Not really- if you look at spec2006 and Geekbench 4 Linux is doing very well in multithreading!
Your opinion?

He seems to be mostly complaining that Linux isn't the same as Windows. Which it's not.

Most software engineers would have diff'd Ubuntu 15.04 and 15.10 and at least figured out which package or kernel update caused the performance regression he's complaining about. At least before they slapped together a big ol' blog entry complaining about it, anyway.

No clue if the perf issue is the implementation or the kernel. I've been writing my own thread pool (linux) for years; if you don't use a thread pool then he might be constantly making/creating threads (which is not horrible if you have a lot of work but not cheap if the work is small per create/destory cycle). I never done much work (thread or otherwise) on windows because I can't stand the tools or os specific api so I will have to depend on some other site (maybe spec2006 is good enough) to determine how the kernel compares.
