What upload speed affects
Upload speed matters when sending video, backing up files, streaming live, joining video calls, or pushing large files to cloud services.
Why upload is often lower
Many residential connections are asymmetric, meaning download speed is much higher than upload speed. That can be normal, but it can still affect creator and remote-work tasks.
