PrivatedetectPerformanceTier

• detectPerformanceTier(): PerformanceTier

  Detect device performance tier Uses multiple heuristics to determine device capability

  Edge Cases:

  • Low-end desktops (2 cores, 2GB RAM) may score as 'medium' due to desktop bonus
  • High-end mobiles (6+ cores, 6GB+ RAM) correctly score as 'high'
  • Very low-spec devices (≤2 cores AND ≤2GB) are always 'low' regardless of platform

  This intentionally favors:

  • Devices with more CPU cores and memory
  • iOS devices (typically good performance)
  • Better network connections (4G/5G)

  Returns PerformanceTier

  Performance tier (high, medium, low)
