RHEL7 Workstation Latency Verses Win10

Semi click-bate title I know but I have noticed there's a general speed difference when it comes to the Windows 10 and the RHEL7 workstations. I'm a bit limited in measurement resources go. I have to use my own scripts that run mtr, wget and few free speed test servers. Given that the workstations all share the same route why would Win10 be 4/5Mbs faster?

I used RHEL's network optimization pdf but there's still that slight difference. I know it's not too much; I can't seem to explain the difference. I did noticed that Win10 is running a higher Intel network driver. The RHEL driver is a few generations behind so maybe that's why? I don't know, has anyone else run across this recently?

I included my simple perl script "site_check". I just picked up perl a few months ago so its probably pretty bad; basically uses wget to test my connection I run it every half hour or so via cron job.
