I'd like to offer my insight. ## Initial examination Running profiler on https://store-beta.rebble.io/?native=true&platform=android yields this:  It seems like there's something running all the time but it's not JS loop....

Nope, it works in unit test: https://github.com/koajs/mount/pull/74 Maybe it's issue with koa-router, I'll report once I find the cause because we can still reproduce it in our project.
