Epoll interesting links

Now that I am working with Go, I was going deeper in Go network APIs and found that Go implements epoll in its library - or, I don't need to do syscalls myself.

Searching for some information, I ended up finding two very interesting articles about epoll internals that clarify some interesting points and I'd like to share (and keep to myself)

Some important context:

• There are two other ways to check for events
• select (very commonly used with sockets)
• poll
• epoll is a faster alternative, specially if you have lots of file descriptors to read from

Shut up and show me the links!

Difference of select, poll and epoll:

• Async IO on Linux: select, poll, and epoll

How epoll works:

• The method to epoll’s madness

What is wrong with epoll:

• epoll is fundamentally broken

Last but not least

Please let me know if you find other links better than those :)
