Let's say I have several files with different sizes (10KB, 100KB, 1MB, 10MB, 100MB). Starting individual transfer of those files over 2MB per second network will return different final throughput based on start and stop timestamp of download or upload that particular file. Naturally, the larger files will get final throughput very close to 2MB, however 10KB, 100KB, and 1MB might be much less.
So final throughputs might become something like: 0.2MB/s 0.5MB/s 1.2MB/s 1.95MB/s.
I know there is an initial connection delay. For example, if I am using
scp, it can take somewhere around 0.2-0.3 seconds to send an empty file. Subtracting initial delay from total time to calculate throughput doesn't produce equal throughput for all files (I can't get delay-free throughput to equal to 2.0MB/s for all files).
Is there anything else that affects this? Does network speed gradually ramps up to 2MB, resulting in smaller files (10KB, 100KB, 1MB) to appear to have smaller final throughput (since data is already sent before fastest rate is available)?
