Program Notes
How we measure, validate, and interpret browser memory performance
Run RAM Stress TestWhat we measure
Our RAM stress test captures allocated buffer size, access throughput, stability under sustained load, and heap pressure when the browser exposes memory APIs. Workloads include sequential scans, random walks, and mixed TypedArray patterns.
Single-channel phases run on the main thread. Multi-channel phases distribute buffers across Web Workers. Auto mode sequences both for a balanced performance portrait.
How scores support memory analysis
Throughput scores correlate with how quickly your tab can touch reserved memory. Stability percentage reveals garbage-collection interference and throttling during the performance window.
Access latency highlights random-pattern sensitivity, which matters for object-heavy applications and fragmented data structures.
Validation principles
We recommend multiple passes with identical settings before drawing conclusions. Document browser version, tab count, and device memory alongside every export.
Browser-based testing reflects JavaScript heap limits and GC behavior in addition to device capability. Use results for relative validation in your browser; hardware-level diagnostics require native tools.
