Chrome update slowed Ajax/Angular Network rendering and loading (1)
I'm not sure if this is still an issue, but I know that Google has continued to ramp up security measures with Chrome. This is especially true with HTTPS and I believe Google is pushing for everything to move to HTTPS. Certificates that are not clean (several criteria for this) present problems and may be requiring extra measures to process. I believe there is an add-on (or built-in) for Chrome dev tools that can break out the TLS processing to show you more detail.
About two weeks ago, a Chrome update crippled users of my angular app. I load a lot of data but the entire single page application loaded in
< 4 seconds but every single user went to
> 40 seconds after updating Chrome 2 weeks ago. I did not experience the problem, but when I upgraded Chrome to
63.0.3239.132, the problem also began for me.
Somewhere between Chrome
64.0.3282.167, there was a change that basically slowed my Angular app to a crawl. It affects loading and rendering across the board and made the entire app almost unusable. I've been looking for the issue for a few days with no joy.
Does anyone have any insight or recommendation on what could cause such a performance degradation?
Here is a screenshot of my network tab. All of this used to be very fast before the Chrome update and now it just crawls.
If I set:
httpProvider.useApplyAsync(true), it alleviates the problem but my application is huge and this causes a lot of erratic behavior in a 5 year old application.
