Performance lab
Proof of scale, generated in your browser: @cynco/ledger-test-data builds deterministic seeded workloads up to 1,000,000 balanced entries, and the virtualized register and account tree render them with a viewport-sized DOM. Timings are measured live — see PERFORMANCE.md for the benchmark inventory these components are held to.
Workload
Pick a workload to generate it in this tab. Generation is one synchronous pass of the seeded generator (it has no incremental API), so the tab blocks until it completes — expect a few seconds at 1,000,000 entries. The register-row projection that follows is time-sliced through the cooperative scheduler in 8 ms slices, so the page stays responsive for that part. Every number shown is a live performance.now() measurement from this session.
