Gigasoft claims ProEssentialsJS delivers over 600 million points per second, dwarfing existing JavaScript charting benchmarks
Executive summary: Gigasoft published a comparison showing its ProEssentialsJS library can render 25 million points at 25 fps (≈625 million points per second), far exceeding LightningChart’s 1 million‑point‑at‑10 Hz test (≈10 million points per second). High‑speed JavaScript charting enables richer, real‑time visualizations in finance, science and analytics; a clear performance edge can drive licensing revenue and influence library selection across sectors.
Who is involved: Gigasoft (ProEssentials), LightningChart, SciChart, Highcharts, ECharts.
Likely next (inference): Third‑party benchmarks will verify the claims; competitors may release optimisation updates; developers may begin evaluating ProEssentialsJS for upcoming projects.
Gigasoft’s press release positions its ProEssentialsJS library as a performance leader, citing internal tests that achieve 625 million points per second versus LightningChart’s published 10 million points per second benchmark. The claim, if validated, could shift developer preference toward ProEssentialsJS for data‑intensive web applications and increase competitive pressure on rivals such as Highcharts, SciChart and ECharts. Independent verification and real‑world adoption will determine whether the announced advantage translates into market share gains.
What's next — scenarios
Inference: scenarios and probabilities are Beyond's assessment, not reported fact.
Technical Validation & Market Disruption (25%)
Significant market share erosion for SciChart and LightningChart as enterprise developers migrate to ProEssentialsJS.
- Independent third-party benchmark report confirming >100M points/sec
- Major enterprise contract announcement using ProEssentialsJS
Marketing Hyperbole / Performance Gap (50%)
Industry skepticism maintains current market leadership for SciChart/LightningChart; ProEssentialsJS remains a niche tool.
- Discrepancy between Gigasoft internal tests and real-world DOM rendering limits
- Failure of developers to report performance gains in large-scale web apps
Integration & Ecosystem Failure (25%)
High performance becomes irrelevant if the library lacks essential documentation or ecosystem support.
- Poor developer sentiment on GitHub/StackOverflow
- Lack of React/Vue/Angular wrapper support
What to watch
- Independent benchmark publications (next 60 days)
- Developer forum discussions regarding ProEssentialsJS stability (next 30 days)
- Public procurement/license updates from Highcharts or SciChart (next 90 days)
