Extreme network slowness, resolved by Cache Storage clear

[edwh]

PWA version 3.3.2.

I've looked at a situation where network requests for Nuxt scripts during initial page load were extremely slow. Using DevTools to bypass the service worker for network requests made everything fast. Then I manually cleared Cache Storage and everything was back to normal (without that bypass setting).

I'm wondering if there might be an issue where the Cache can get so full of stuff that the service worker caching starts to really struggle.

Anyone seen anything like this?
