Upload speed is rather slow despite FTTH fibre optics

Good morning, I've recently moved and am now the proud owner of an FTTH fibre optic Internet connection. I just ran a speed test, and my download speed is at 30 MB/S, while upload speeds have reached...

Hey cloudres, thanks for your post today.

 

To provide some context on syncing speeds, keep in mind that most internet service providers measure connectivity speeds in kilobits and megabits (KB and MB), while most cloud storage providers measure the size of data in kilobytes and megabytes (also KB and MB). 

 

The difference between the units is: 8 bits = 1 byte, so seeing speeds of 15,000 KB/sec (or 15 MB/sec) from Dropbox is equal to around 120,000 KB/sec (120 MB/sec) from a speed test.

 

This can sometimes make it look like Dropbox is running slower, but the only difference is in the measurement unit.

 

I hope this helps, but let me know if you have more questions.

Hi Hannah,

Just keep in mind that B, KB, MB, GB, etc. are all multiple of Bytes, NOT bits!!! (or that's the rule, at least - incorrect enlabel is always possible though) The units, like b, Kb, Mb, Gb, etc. are multiple of bits. 😉 The difference is in the unit letter capitalization!!!

There are other information units differences. While KB, MB, Kb, Mb, etc. are decimal representations, KiB, MiB, Kib, Mib, etc. are binary representations. Sometimes the units are misused (or ever mixed) by some providers. For example Dropbox use binary units as values on Dropbox site (for file size, available and engaged user space, etc), while the labels are decimal (KB, MB, GB,...) - completely wrong!!! 😯 The same like to measure a temperature in Fahrenheit, but labeled as ℃ or opposite. 🤣 Keep correct unit labels (on the forum at least - whenever possible).
