Mediocre score on PageSpeed Insights

PageSpeed Insights score of official vsf demo is 37/54 mobile/pc.
https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fdemo.vuestorefront.io%2F

Is that score important?
Why this score is low? Page seems to be fast.
Will any actions be taken to improve the score in future?

Hey!

It’s a known issue and nothing to worry about. The difference between local Lighthouse runs and those from PageSpeed insights comes from the fact that the latter is not supporting HTTP/2. Vue Storefront highly relies on code-splitting and prefetching which is a standard type of optimization for HTTP/2 but something that can lower the score on HTTP/1 because of it’s parallel connections limit. TTI metric seems to be affected the most.

Thankfully it’s something that Chrome team is working on and should fix soon - https://github.com/GoogleChrome/lighthouse/issues/7326

For now i recommend using local Lighthouse runs to measure the performance.
