I noticed that cached files served from a service worker take way to much time according to the Chrome devTools Network tab which shows Size=(from ServiceWorker) and Time=139ms for a small image file (60x60).
The fetch handler within my service worker has logged a cache hit for this image file so I am sure that the file was served from the cache and not from the network.
Is the Time value displayed in the chrome devTools wrong or are 139ms within the range of expected values?
