How We Improved the Performance of a Userspace TCP Stack in Go by 5X

In this article, the author discusses how they improved the performance of a userspace TCP stack in Go by 5X. They explain that throughput is an important measure of network connection quality and describe how Coder v2.12 includes several networking improvements that increase throughput dramatically. The author delves into the details of these improvements, including increasing TCP buffers, implementing HyStart for better congestion control, and optimizing packet processing within the Coder process. They conclude by stating that while significant progress has been made in network performance, they will continue to work on improving it further.
