  • Removed pool-related fields/methods from Message.cs
  • Removed Recv(Message, int expectSize) overload from Socket.cs

Changed

• Simplified Message class - Cleaner structure after removing pooling-related code
• Consolidated to 4 message buffer strategies
  • ByteArray (Baseline)
  • ArrayPool (recommended for ≤1KB)
  • Message
  • MessageZeroCopy (special cases only)

Documentation

• Complete benchmark documentation update
