System Engineering & Architecture

Welcome to my personal knowledge base. Here I document various aspects of microservices, high-load systems architecture, and Linux kernel tuning.

When dealing with long-fat networks (LFN), default Linux core network parameters might not be sufficient. To achieve maximum throughput, one should focus on net.ipv4.tcp_rmem and net.ipv4.tcp_wmem arrays.
