COMMON QUESTIONS
Why is upload time often longer than download time?
Many consumer internet plans provide less upload capacity than download capacity. Cloud services, backups and live streaming all compete for that upstream bandwidth.
Does the calculator include overhead?
Yes. The efficiency control lets you reduce the theoretical line rate to model protocol overhead, Wi-Fi conditions and destination-server limits.
