New UI is slower on the task page (when data is cached) |
|||
Issue descriptionhttps://chromium-swarm.appspot.com/task?id=32a33359c341d310&refresh=10&show_raw=1 -- Takes 3.77s https://chromium-swarm.appspot.com/oldui/user/task/32a33359c341d310 -- Finished 747ms. I've attached the output from the network tool in developer tools. This appears to be to do with caching and the fact it has to render stuff locally with javascript. On the first load, the new UI is faster. However when switching between multiple different tasks quickly (that you have seen before) the old UI is *much* faster.

See #667631. The screenshots attached seem to show most of the time is actually waiting for the etag checks (i.e the requests whose response is 304), and I don't know how to fix that other than lay better fiber to Australia. (In North Carolina, USA, I see those 304 requests take about 40ms, rather than ~400ms) Again, this could be because once you have dev tools open, the cache isn't used as much: https://bugs.chromium.org/p/chromium/issues/detail?id=667631#c1 Let me know what you experience, both with dev tools and without dev tools, now that caching is enabled.
