1865098 - open.spotify.com cache grows high with 60k cache/morgue files and causes slow startup

Status: NEW

(Core :: Storage: Cache API, defect, P3)

Description

[Kagami Rosylight [:saschanaz] (they/them)]

Not clear whether this is a site problem or a browser issue, but there's so many cache files (1 GB+) and reading it takes a lot of time, which causes:

1. slow browser startup (takes 2+ minutes on my Surface Pro 7)
2. slow Cache API responses (takes near one minute for caches.open("data-cache-v1") and also the cache.keys(), which returns 1k+ keys)
3. failure to inspect the cache storage in devtools; it says "No data present for selected host"

At least one of the retrieved cache entry had max-age=0 but somehow that's being kept forever. (It's not clear how long exactly the entry was there as I don't know any way to tell it)

Hmm, in comparison, the profile in my desktop only has 600+ files with 12 MB space. cache.keys() for data-cache-v1 returns 292 keys.

Uh, maybe the culprit is workbox-precache-v2-https://open.spotify.com/, which has 60,600 keys in the affected profile 🙂
