LogCabin uses its event loop for network operations but then hands requests off to threads to process. I started out with libevent2, but the problem is it doesn't deal with having multiple threads very well (error-prone and inefficient). It's also not as well-documented as the man pages for epoll, so I ended up using epoll directly instead. What was really lost in the libevent2 -> epoll conversion was platform independence, but I think it might be better to get that back through well-placed #ifdefs or relying on some other library; I wouldn't go back to libevent2.

We're using libev (actually libev++ which is cross-platform, has a decent underlying C impl, and a C++ bridge API). It seems to work well and is fast and cross platform. It can be a little tricky to figure out what is going on with the C++ API sometimes due to how the author tacked it on using macros.

Did you consider libuv?

[ongardie]

I guess the answer is no, I haven't really looked at it. Anyone have experience with it in a large-ish project outside of Node?

[apaprocki]

Yes -- it is very straightforward to use and "just works". (It is also used in a similar way as found in Node in the luvit project: https://github.com/luvit/luvit)
