Additional, advanced multiplexing topics

• DbDataSource
• Zoom into how the write loop works
  • Never yield for I/O - only when there are no longer any commands
  • Writing completes synchronously under normal circumstances. When it doesn’t, we do ContinueWith etc.

Multiplexing tweaks

• Write Coalescing Buffer Threshold
  • Stop coalescing when we’ve reached a threshold (1000 bytes).
  • Ethernet MTU is 1500, but jumbo frames are 9000.
• Write Coalescing Timeout
  • Wait a bit even if there aren’t any pending commands.
  • Sacrifice latency for throughput
