Memory usage

• Memory usage before optimization:
  • Minimum: 67.8 MB
  • Maximum: 1527 MB
  • Difference (range): 1527 − 67.8 = 1459.2 MB

• Memory usage after optimization:
  • Minimum: 68.2 MB
  • Maximum: 206 MB
  • Difference (range): 206 − 68.2 = 137.8 MB


• Reduction in memory range:
  • Absolute change: 1459.2 − 137.8 = 1321.4 MB
• Percentage improvement:
  • Formula: (absolute change / initial usage) * 100
  • (1321.4 / 1459.2) × 100 ≈ 90.57%

Rendered DOM nodes

• Number of DOM nodes before optimization:
  • Minimum: 3,088
  • Maximum: 966,894
  • Difference (range): 966,894 − 3,088 = 963,806 nodes
• Number of nodes after optimization:
  • Minimum: 3,188
  • Maximum: 9,415
  • Difference (range): 9,415 − 3,188 = 6,227 nodes
• Reduction in the range of nodes:
  • Absolute change: 963,806 − 6,227 = 957,579 nodes
• Percentage improvement:
  • Formula: (absolute change / initial usage) * 100
  • (957,579 / 963,806) × 100 ≈ 99.35%
