So here's the things to consider: | |
* Do not preallocate a read buffer per socket. | |
Either use polling or use a shared buffer pool. | |
* Avoid statefulnews, e.g: | |
- In windows, you can't use multiple completion ports with a handle. | |
- On unix, a socket is either in blocking or non-blocking mode | |
This creates problems when you want to share a handle with other processes | |
or between threads. For example, you might want to switch stdout to | |
non-blocking, but if stdout was inherited and shared with the parent | |
process, the parent process might not expect this and crash or malfunction. |
