I have found that some LAN installations work but have problems, (many retransmissions).
I thus would like to be able to plug a "Super Looper" at a LAN wall jack and test the actual throughput speed.
Super Looper is sold by Amazon: https://www.amazon.com/Smartronix-Su.../dp/B001EHRTNE
Can you add a SuperLooper (full duplex) addition to LAN Speed test Lite?

On my MacBook Pro I am running about 477Mbps write and 3.600Mbps read. To my Raid6 NAS server the numbers drop to 40Mbps write and 90Mbps read. I have a 10m CAT6 cable. I do not understand the slower read speed. I have a Synology DS411j NAS.
