Benchmarks
To find out how quick we can Transfare files we edited the Server component to measure time from the File creation message to the last file part. We collected the time needed for several test files (5 MB, 50 MB, 100 MB, 200 MB, 1000MB). The client and the Server were executed on the same machine (i7 7500u, 16GB RAM, SSD) and the Packages send trough the Loopback interface.
In this graph you can see that with the margin of error the time needed to transfer files grows linearly with file size. The achieved speed was overall 24.64 MB/s.
For the next figure, we modified the Server, to measure the time from the creation of the FilesystemServer object to the first message it received. This test was run multiple times. 
All results are between 0.00467s and 0.001724s. This is a huge span. But we think that this is through differences in the scheduling of the machine running the Benchmark.
To Compare the send bytes with the file size, we created a simple function. f(x, a, z) = (2 a + 1200 ⌊x/100⌋ + 10 x + z + 2960). It's parameters are:
- x := The actual length of the file send
- a := The length of the FID (path + filename)
- z := The length of the password
To visualize it we fixed a and z (a = 40, z = 8).
We also added a linear reference function to the plot. In this graph you can see that the send bytes grow linear with the Filesize.
