The book "Performance Analysis and Tuning on Modern CPU"

My book is a 170+ page guide for optimizing the performance of applications that run on modern CPUs. It combines the knowledge of many experts from different industries, to whom I'm very thankful. Engineers from Google, Facebook, leading HFT, and game development firms helped me shape this book

DarkFlare

DarkFlare Firewall Piercing (TCP over CDN) 

It has two parts: a client-side proxy (darkflare-client) that encodes TCP data into HTTPS requests and sends it to a Cloudflare-protected domain, and a server-side proxy (darkflare-server) that decodes the requests and forwards the data to a local service (like SSH on port 22). It’s protocol-agnostic, secure, and uses Cloudflare's encrypted infrastructure, making it stealthy and scalable for accessing internal resources or bypassing network restrictions.
