Why is my actual LAN speed lower than test speed?

Aug 10, 2015 11:50AM PDT

I'm a noob when it comes to networking, so I'll apologize in advance for not knowing/finding the answer to what is probably an obvious question.

I've used Tutusoft LAN Speed Test to examine the transfer speed of my LAN and the tests come back (from one PC to another) at around 160 MBps Write and 300 MBps Read. When I actually transfer a file to and from the same PCs the max transfer rate (Write) is about 11 MBps. Why the huge disparity between the test and the actual transfer?
