How to understand the 'Send Speed' in YABS?
I'm a bit confused about Send Speed in YABS. Is that the upload speed of the VPS correlating to the download speed of a user fetching a file from this VPS?
In this case, for someone in London, I would expect a download speed of 262 Mbits/sec from this VPS, correct?

Many Thanks,
Comments
YABS uses 8 parallel streams when testing send speed from the VPS. If you had 8 people downloading files from your VPS from one of those providers at that datacenter, you can approximately reach those speeds.
Depending on how the file is served you might not reach those speeds on a single file download.
They can reach it, but depending on how its routed, it may be worse or even better.
Its an indicator though, how good the connectivity is.
anyway, only Geekbench 5 Benchmark counts!
Correct.
