125 | EV by default uses select, which makes it hard to write efficient servers, |
|
|
126 | especially if the number of active conencitons is much lower than the open |
|
|
127 | ones. GNU/Linux systems have a more scalable method called "epoll", which |
|
|
128 | EV can use. For this to work, both your kernel and glibc have to support |
|
|
129 | epoll, but if you can compile it, the detection will be done at runtime, |
|
|
130 | and EV will safely fall back to using select when epoll isn't available. |

131 | If unsure, accept the default. |
