/ Speed Test
Check your internet speed
Download, upload, latency, and jitter — measured from this browser to Cloudflare’s network.
Cloudflare receives your IP and anonymized measurement data for their research. A full test can use up to about 200 MB of data.
Network quality score
Cloudflare’s AIM scores rate how this connection fits common uses — streaming, gaming, and video calls — based on the numbers above.

Latency detail
Idle latency is your baseline. Loaded latency is what happens while the pipe is busy downloading or uploading — useful for calls and remote desktop.

Bandwidth progress
Each point is a transfer sample as the test ramps file size. Spikes and dips are normal on shared Wi‑Fi.

What these numbers mean
Download speed is how fast files and pages pull in. Upload is what you send — backups, camera feeds, and cloud sync care about this more than most people expect.
Latency and jitter matter for phone systems and video meetings. High jitter on a “fast” circuit still makes calls choppy.
If Greenville office Wi‑Fi looks fine on a phone but rough on this test — or the other way around — that’s a clue. Call (864) 335-9223 and we’ll help you read it, or request a call.
Speed test questions
How accurate is this speed test?
It measures your path to Cloudflare’s edge network from this browser. Results can differ from your ISP’s marketing number — Wi‑Fi, VPN, other devices, and which server you hit all move the needle. Use it as a check, not a courtroom exhibit.
Will this use a lot of data?
A full run can use up to about 200 MB. That’s normal for a thorough bandwidth test. Avoid starting one on a metered mobile hotspot unless you mean to.
What does Cloudflare see when I run the test?
Cloudflare receives your IP address (used to estimate city/country and ISP ASN) and anonymized measurement data for their internet quality research. PremierePC does not store your speed-test results on this page.
My numbers look low. What should I do?
Retest on a wired connection if you can, close big downloads, and turn off VPN. If upload or latency is still rough for phone systems or cloud apps, call us at (864) 335-9223 — we’ll help sort circuit vs Wi‑Fi vs gear.
