  - setTcpFastopen
```
public EpollServerChannelConfig setTcpFastopen(int pendingFastOpenRequestsThreshold)
```
    Enables tcpFastOpen on the server channel. If the underlying os doesn't support TCP_FASTOPEN setting this has no effect. This has to be set before doing listen on the socket otherwise this takes no effect.
    
    Parameters:
    
    pendingFastOpenRequestsThreshold - number of requests to be pending for fastopen at a given point in time for security.

```
public EpollServerChannelConfig setEpollMode(EpollMode mode)

    Description copied from class: EpollChannelConfig
    
    Set the EpollMode used. Default is EpollMode.EDGE_TRIGGERED. If you want to use DefaultChannelConfig.isAutoRead() false or DefaultChannelConfig.getMaxMessagesPerRead() and have an accurate behaviour you should use EpollMode.LEVEL_TRIGGERED. Be aware this config setting can only be adjusted before the channel was registered.
    
    Overrides:
    
    setEpollMode in class EpollChannelConfig
