VS Code instruction counts
Tests ranked by user-space instructions in the inspected process during the scenario. Higher counts indicate more CPU work; they are not evidence of a memory leak.
CI runs each scenario once, with a fresh VS Code instance per test. Application startup is excluded. Background work and scenario duration can affect the counts. Compare results collected with the same architecture and settings.
150 tests measured; 8 with unavailable instruction counters. Unavailable values are excluded from the chart.
