They nearly got all of the right. This is not right however:
Disable all features with “Offload” in the name
You definitely want Large Receive/Send and TCP Chimney Offload options disabled, but you want Offload IPv4/TCP/UDP Checksum options enabled (for transmit and receive, if your drivers breaks it up) if you're using Intel LAN on your motherboard or a PCIe/PCI network adapter.
IPv4 Checksum Offload: Enables the adapter to compute the IPv4 checksum of packets instead of the host OS, which can help increase adapter performance while also reducing CPU utilization.
TCP Checksum Offload: Allows the adapter to compute the TCP checksum of outgoing packets rather than the host OS, which can help increase transmission performance while also reducing CPU utilization.
UDP Checksum Offload: Enables the adapter to compute the UDP checksum of outgoing packets instead of the host OS, which can help increase transmission performance while also reducing CPU utilization.
Trasmit/Receive Buffers don't work as simply as they think. Reducing them as low as possible like he suggests won't magically remove 'network delay'. First of all, buffer settings are very specific to their respective network adapter and driver, so ham-handedly giving recommendations for them is foolhardy. Nearly every network adapter I've ever personally used had practically 0 documentation on buffer settings, and the ones that did gave very stern warnings against changing them from the defaults and it was mainly something intended for networking professionals. Unless you can provide statistically significant data that proves changing these settings is an improvement for your specific situation, I would highly recommend against altering these from the default values.
Also, you have to setup your Windows environment to match the settings of your network adapter. I find TCP Optimizer to be the easiest way to do this. Here are my settings:
*Note: Intel Virtualization Technology must be enabled in the BIOS for NetDMA and Direct Cache Access to work.
