Class TransportConfig.RegisteredBuffersConfig

java.lang.Object
express.mvp.myra.transport.TransportConfig.RegisteredBuffersConfig
Enclosing class:
TransportConfig
public static final class TransportConfig.RegisteredBuffersConfig extends Object
Configuration for the registered buffer pool.

Controls the number and size of pre-registered buffers used for zero-copy I/O.

Sizing Guidelines

  • numBuffers: Should match expected concurrent I/O operations. Rule of thumb: 2x expected concurrent connections.
  • bufferSize: Should match typical message size plus overhead. Common values: 8KB-64KB depending on protocol.

Memory Usage

Total memory = numBuffers × (bufferSize rounded up to page boundary)
