We have a 100x100 Ethernet over copper Internet connection. Your download test file size caps out at 200 MB which is barely OK (would be better if could do 1 GB). But your upload test file size caps out at 50 MB which is downright tiny when you have an 100 MB/s upload link speed. To put this in perspective my firewall bandwidth monitoring tool samples bandwidth every 5 seconds. The 50 MB upload test barely shows up... not good. We would love for both the download and upload file sizes to max out at 1 GB so it shows up clearly on our firewall monitoring utilities.
