Summary

fix #29642

Performance Optimization Configuration

  1. Connection Limits
  • max_filedescriptors 65536 - Support more concurrent connections
  • maximum_tcp_connections 1000 - Maximum TCP connections
  1. Timeout Configuration (optimized for image requests)
  • connect_timeout 2 minutes - Connection timeout
  • request_timeout 10 minutes - Request timeout (sufficient for large image downloads)
  • read_timeout 10 minutes - Read timeout
  • client_lifetime 24 hours - Client connection keep-alive time
  1. Connection Reuse (improve performance)
  • server_persistent_connections on - Server-side persistent connections
  • client_persistent_connections on - Client-side persistent connections
  • persistent_request_after_timeout 30 seconds - Reuse connections after timeout
  1. Request Protection
  • quick_abort_min/max/pct - Prevent near-completion requests from being interrupted
  • client_idle_pconn_timeout - Idle connection timeout
  1. Memory Cache
  • cache_mem 256 MB - Memory cache size
  • maximum_object_size_in_memory 512 KB - Suitable for small icons/avatars
  1. DNS Optimization
  • dns_nameservers 8.8.8.8 8.8.4.4 - Use public DNS servers
  • dns_timeout 30 seconds - DNS timeout

These configurations should significantly improve timeout issues when handling high-concurrency image requests. You need to restart the squid service for the changes to take effect.
