>> Default MTU Configuration:
Setting MTU size is a process of trial-and-error: start with the maximum value of 1500, then reduce the size until the problem goes away. Using one of these values is likely to solve problems caused by MTU size:

    1500. The largest Ethernet packet size; it is also the default value. This is the typical setting for non-PPPoE, non-VPN connections. The default value for NETGEAR routers, adapters and switches.
    1492. The size PPPoE prefers.
    1472. Maximum size to use for pinging. (Bigger packets are fragmented.)
    1468. The size DHCP prefers.
    1460. Usable by AOL if you don't have large email attachments, etc.
    1430. The size VPN and PPTP prefer.
    1400. Maximum size for AOL DSL.
    576. Typical value to connect to dial-up ISPs.
   
Value : 1464 + 28 = 1492 >> Optimal MTU

Check Fragmentation and other errors using : netstat -s

>> QoS Packet Scheduler Windows 100%
Regedit:

    Click on Start in the lower-left corner of your screen and type Regedit in the search box and press Enter on your keyboard
    In Regedit click your way through HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows
    Right click on the Windows map and select New and Key from the dropdown menu and name the new map Psched
    Double-click on the new Psched map and right click in the empty white screen on the right
    Select New and DWORD (32-bit) Value from the dropdown menu
    Name the new Dword Value NonBestEffortLimit
    Right-click on your new NonBestEffortLimit key and select Modify from the dropdown menu
    In the Value Data field make sure the value is 0 so the reserved bandwidth percentage is set to 0% (you can change the value to any percentage you want the reserved bandwidth to be, from 0 to 100)
    Click OK and restart your PC to make the changes

How To Restore The 20% Reserve

If at a later date you decide you no longer like removing/modifying the 20% reserve, you can simply edit the NonBestEffortLimit key in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched and enter 20 in the Value data box to restore the reserve back to its default 20%; or you can delete the whole Psched folder, which makes it like you never modified the reserve in the first place (it goes back to its default 20%). Then restart your computer and you are good to go.
