Jitter
Measured against the nearest Cloudflare server, so this is the speed of your connection to the internet, not to this site.
A test uses up to about 180 MB on a fast connection: mind a metered or mobile data plan.
Details
Latency under load is measured while the download or upload runs. Much higher than at idle, it means the router or the line buffers too much (bufferbloat): calls and games lag as soon as someone downloads.
