About
FAST.com speed test gives you an estimate of your current Internet speed. You will generally be able to get this speed from leading Internet services, which use globally distributed servers. Download speed is most relevant for people who are consuming content on the Internet, and we want FAST.com to be a very simple and fast speed test. When you click the “Show more info” button, you can see your upload speed and connection latency (ping). FAST.com provides two different latency measurements for your Internet connection. “unloaded” and “loaded” with traffic. The difference between these two measurements is also called “bufferbloat”. To calculate your Internet speed, FAST.com performs a series of downloads from and uploads to Netflix servers and calculates the maximum speed your Internet connection can provide. FAST.com will test Internet speed globally on any device (phone, laptop, or smart TV with browser).

About
PerfDelta is a web-based website speed testing and monitoring service for SEO specialists, agencies, and in-house web teams. Its free test scans up to three pages on mobile and desktop, combining real-user Core Web Vitals from the Chrome UX Report with Lighthouse lab measurements. Reports compare a site with up to two competitor domains and a benchmark of previously tested sites, show page-weight breakdowns and request timelines, identify site technologies, and estimate savings in prioritized recommendations naming affected files. Paid plans add scheduled monitoring, performance budgets, email alerts, report history, and PDF exports; Agency and Scale plans also provide CSV export, public dashboards, and a REST API. MCP access lets compatible AI agents request tests and retrieve results. Reports can be shared with clients for performance audits and ongoing site work.
