They mention that this is using a polling architecture so each core is using 100% cpu even when idle. I've worked on high performance systems architected around polling before, but assumed that would be prohibitively costly these days now that cpu's have really advanced power management capabilities. Is polling architecture still viable for large scale cloud computing given costs of energy consumption? Years ago cpu'…
We plan to reduce power usage on low load eventually.
For everything else I'd just use Python or PHP as they are mostly fast enough.
I am planning to write a framework in Rust when I have the time though as I find it an interesting language and as a web dev it's my area, I'll definitely be looking at how you approached stuff ;).
