66 | This module is very fast and scalable. It is actually so fast that you |
|
|
67 | can use it through the L<AnyEvent> module, stay portable to other event |
|
|
68 | loops (if you don't rely on any watcher types not available through it) |
|
|
69 | and still be faster than with any other event loop currently supported in |
|
