it wasn’t meant to be fast - that is my 13yr-old son#1 having the time of his life.
Before I put it off the road and err race-prepared it ( we just unbolted everything not strictly req’d) it was known as the Atomic Skateboard. I could go into a roundabout behind two other cars and emerge first, having taken one on the outside and one on the inside 
Sadly such behaviour was deemed incompatible with retaining a license so I screwed the nut and got something more boring for going to work in,
And yet not so slow after all, a great toy for a 13 year old, cheers
Well it was until he rolled and flipped it at a grass-test.
I was sitting beside him “supervising” - not particularly effectively.
Still we did manage to drive it back on to the trailer to take it home. His mother was not impressed and seemed to think it was all my fault. Women are strange. Especially when I suggested that we use her Polo for the next event in a fortnight.

Ebough remninicing about how I failed to raise Jackie Stewart II, how are we doing with filling this 50Gb?
I suppose we wont know until puts start failing but we can still get

Getting a little above my pay grade but searched how to create random files and found the following script and altered it to suit the less than 10mb. when it runs it just returns command not found for the 10 loops. what command?
mkdir upload-files
cd upload-files
for n in {1..10}; do
dd if=/dev/urandom of=file$( printf %03d "$n" ).bin bs=1 count=$(( RANDOM + 1024 ))
done
random better than urandom
but if linux then try
#!/bin/bash
mkdir -p ./upload-files
cd ./upload-files
for n in {1..10}; do
openssl rand -out sample$n.txt -base64 $(( 2**20 * 3/4 ))
done
random worked but the files are of unknown type. I will go with yours 
Can’t publish links, but reporting catting and putting working nicely!!
just found this for monitoring network traffic in bash on ubuntu and thought I would share
$sudo apt install speedometer
$speedometer -l -r wlan0 -t wlan0 -m $(( 1024 * 1024 * 3 / 2 ))
gets you this nice graph change the wlan0 to your desired interface
It has already been reported as issue
I get the same error.
Does this mark the end of testnet, or is there still a reason to continue?
Hesitate to do so because of your comment elsewhere in this forum 
But, even worse using ‘time’ on a (neglected) LInux machine…
‘Timethis’ in Windows is from the ‘Windows 2000 Resource Kit’.
Predates the inception of MaidSafe on 22 February 2006.
If executed then at noon, “Elapsed time” up to this ‘50gbRound2’-test net would have been:
8,848,800 minutes
Ah but it’s worth the wait!
It’s well behaved aside from that 6th file error… and unclear how long that’s been there… could have been a copy paste error… but I’m an optimist
Everything else looks as expected…
The only missing bit I wonder is that there could do with being a validation check if hidden .files exist, as the user might not be intended for those to be included to a recursive upload.
Getting an error on that file as well

consistency is good
If it’s just that one that’s failing perhaps that’s a good sign too.
