libuv - libuv 只是 POSIX 系统上 libev 的包装器吗？

Question

我真的很困惑 libev 和 libuv。

libuv 只是 POSIX 系统上 libev 的包装器吗？

如果不是，它的区别在哪里？

Answer 1

不再，因为 libuv-v0.9

Here is the libuv github issue它跟踪从 libuv 中删除 libev。

删除的原因是，引用上面链接的问题:

In case any project watchers are wondering, libev served us well but:

1. It only supports level-triggered I/O. On Linux, we want to use edge-triggered mode - it cuts down the number of syscalls by a substantial margin.

2. libev's inner loop does a lot of things we don't really need. Gutting the inner loop like we did in 649ad50 gave a 40% performance increase on some benchmarks.
