171 | The previously mentioned Linux AIO backend is experimental and will not |
|
|
172 | be used unless requested explicitly. You can, howeer, choose to make ti a |
|
|
173 | recommended basckend, which means it will be chosen if available even when |
|
|
174 | not explicitly asked for, in preference to epoll on GNU/Linux. This option |
|
|
175 | is likely temporary. When unsure, accept the default. |
