Title

Add connection pooling support to AsyncTcpConnection

Description

The async client currently uses a single connection per client instance. For high-throughput scenarios, connection pooling would improve performance and reliability.

Tasks

• Design connection pool architecture:
  • Configurable pool size
  • Connection health checking
  • Idle connection timeout
• Implement connection pool:
  • Connection acquisition/release
  • Load balancing across connections
  • Automatic reconnection on failure
• Add configuration options:
  • Min/max pool size
  • Connection timeout
  • Keep-alive settings
• Add metrics:
  • Active/idle connections
  • Connection wait time
  • Connection errors
• Test pool behavior:
  • Under load
  • With connection failures
  • Pool exhaustion scenarios
