When you play video games in network (locally or on Internet), the latency is very important. It corresponds to the response time between when you press a button or move the mouse and when the desired action is executed in the game. By default Windows combines small packets into one before sending them. By disabling this feature, small packets will be transferred immediately without delay, thus reducing your latency. In this tutorial I will show you which steps you need to perform inside Windows 7 in order to make this work.
Intel recently spent a few bucks (more like $125 million) and acquired the InfiniBand network business from QLogic. InfiniBand has been around for ten years now and is a storage and communication link in HPC, Oracle RAC and other fewer known environments. It has been designed to sustain scalability, low latency and high throughput.
