Bandwidth

The amount of data you can squeeze through a connection is often titled "bandwidth". You can test network bandwidth with iperf.

Here's a list of select link speeds in bit/s and byte/s for comparison. The table contains estimates of real life net data rates, not the theoretical maximum data rate.

Units:

• b = bit
• B = byte
• 1Kb = 1000 bit
• 1KB = 1000Byte
• 1KiB[(many people incorrectly assume that a Kilobyte is 1024 Byte, instead that'd be a Kibibyte)] = 1kB = 1024 Byte.
• 1MB/s = 1E6[(1E6 in scientific/engineering notation means 1·10⁶ = 1 000 000)] byte per second

If the bandwidth needed is not symmetrical, ↓ means downstream (server→client) and ↑ means upstream (client→server). This is always per User.
