New release with improved CPU performance

Hi all,

Just wanted to let you know that release 2020.8.0 improves the CPU usage of cloudflared quite a lot, especially for high-traffic tunnels. Here’s a graph of one of our cloudflareds – you can see the upgrade pretty easily :slight_smile:

Looks awesome!
Unfortunately I’m personally not using cloudflared anymore for now as Argo’s scope can’t be limited yet to just specific subdomains.
Argo is quite powerful combined with Workers from my previous experiences with it, so fingers crossed for there to hopefully be some scope customisation options in the future.

@achalmers I’m curious if you’ve tried 2020.8.1 or newer yet, which are now compiled with Go 1.14. There was a bunch of performance work in memory allocation and defer handling in this most recent Golang release!
