Going way back to Steve Souders original orielly book on performance his first rule was simple, make less requests. As a result we did things like Base64 encoding files into our HTML, but is that really a good approach these days?

GitHub - Microsoft/ethr: Ethr is a Network Performance Measurement Tool for TCP, UDP & HTTP.
Ethr takes inspiration from existing open source network performance tools and builds upon those ideas. It is very similar to iPerf3 for bandwidth measurements for TCP. iPerf3 has many more options for doing bandwidth measurements such as throttled testing, richer feature set, while Ethr has support for multiple threads, the ability to scale to 1024 or even higher connections, multiple clients to a single server etc. It is similar to latte on Windows or sockperf on Linux for doing latency measurements.

Ethr is natively cross platform, thanks to golang, as compared to compiling via an abstraction layer like cygwin that may limit functionality.
