Frequently Asked Questions
Why would I need a 1GB test file?
1GB files are used for real-world speed testing: ISP bandwidth verification, cloud storage upload limits, backup system testing, and verifying that your application handles multi-gigabyte files without crashing or timing out.
How long does it take to download 1GB?
On a 100 Mbps connection: ~80 seconds. On 1 Gbps fiber: ~8 seconds. On 10 Mbps: ~13 minutes.
My download keeps failing at 1GB — why?
Common causes: browser timeout settings, proxy/firewall limits on file size, ISP throttling, or insufficient disk space. Try using curl or wget for more reliable large downloads.
