P-000047-01 Improve POS performance when order entry becomes slow or laggy

← Back

Used for Trouble: T-000047

1) Confirm performance symptoms

  • Verify lag occurs during order entry, not full system freeze
  • Ask when slowdown is most noticeable (idle vs peak)
  • Note whether lag is constant or intermittent

2) Check system resource usage

  • Open Task Manager
  • Review CPU, memory, and disk usage
  • Identify any process consuming excessive resources

3) Close unnecessary background processes

  • Stop non-essential applications
  • Pause or disable automatic updates during business hours
  • Recheck performance after cleanup

4) Verify application cache and temp usage

  • Close POS application
  • Clear application cache or temp directories if supported
  • Restart application cleanly

5) Check network latency

  • Verify stable network connection
  • Test response time to server or CSC if applicable
  • Resolve latency before further tuning

6) Review uptime and restart policy

  • Check how long terminal has been running
  • Reboot terminal if uptime is extended
  • Consider scheduled daily restarts during off-hours

7) Verify hardware suitability

  • Confirm terminal meets minimum hardware requirements
  • Check for aging or underpowered systems
  • Plan hardware refresh if lag is persistent

8) Test under normal load

  • Enter multiple test orders
  • Confirm responsiveness is restored
  • Monitor during moderate traffic

9) Escalation check

  • If lag continues:
  • Capture performance metrics
  • Review application logs
  • Escalate to systems or application support
