XIU2/CloudflareSpeedTest
"Preferred IP" Test Cloudflare CDN latency and speed
"Preferred IP" Test Cloudflare CDN latency and speed, get the fastest IP (IPv4 / IPv6)! In addition, other CDN / website IPs are also supported. Many foreign websites are using Cloudflare CDN, but the IPs assigned to visitors from mainland China are not friendly (high latency, high packet loss, and slow speed). Although Cloudflare discloses all IP segments , it would be exhausting to find the one that suits you among so many IPs, so this software came into existence. -

PackageCompiler
Compile your Julia Package
...All subsequent calls within that same session use this fast compiled function, but if you restart Julia you lose all the compiled work. PackageCompiler allows you to do this work upfront — further ahead of time — and store the results for a lower latency startup. You can save loaded packages and compiled functions into a file (called a sysimage) that you pass to Julia upon startup. Typically the goal is to reduce latency on your machine; for example, you could load the packages and compile the functions used in common plotting workflows using that saved image by default. In general, sysimages are not relocatable to other machines; they'll only work on the machine they were created on. -

cloudflare-speed-cli
CLI for internet speed test via cloudflare
cloudflare-speed-cli is a Rust-based command-line internet speed testing tool that interfaces with Cloudflare’s public speed test endpoints, letting users measure download and upload throughput, latency, and more from a terminal. It presents results in an interactive text-user-interface (TUI) that charts real-time metrics as tests run, making it easy to visually inspect performance trends without leaving the console. The tool also stores historical test results and can export measured data as structured JSON for scripting, logging, or integration with automation tools. ... -

CFnew
Cloudflare Workers-based proxy deployment project
...It supports multiple proxy protocols and lets users manage paths, preferred IPs, and output formats through a more convenient interface. The project stores configuration through Cloudflare KV, which allows changes to take effect without redeploying the worker each time. It includes latency testing tools and automated format detection so different clients can receive compatible subscription output. cfnew is designed for users who need a flexible Cloudflare-backed node configuration system rather than a simple static link generator. Because it deals with proxy infrastructure, it should be used only in lawful environments and according to applicable service terms. -

Napkin Math
Techniques and numbers for estimating system's performance
...It collects practical numbers, benchmark-style measurements, and mental models that help engineers make fast back-of-the-envelope calculations. The project is useful for questions like how much memory throughput matters, how long storage operations may take, what network latency to expect, or how expensive logging could become at high request volume. It treats these values as rounded numbers for reasoning rather than exact performance guarantees. The repository is especially useful for system design interviews, architecture planning, capacity estimation, and infrastructure cost discussions. It encourages engineers to practice estimation as a skill so they can reason about systems before building or benchmarking them. -
