Code Push Update is very slow on Android and iOS

[agrawalsurabhi89]

Thanks so much for filing an issue or feature request! Please fill out the following (wherever relevant):

Steps to Reproduce

1. On Load of the app, we are calling checkforUpdate() to check if there is an update present or not.
2. if user clicks on Update will download the bundle and we are showing the loader by the time bundle is download in the device.
3. Once its downloaded the updated we are showing that its update

Expected Behavior

The update should happen very quickly, sometime it get stuck in the update and takes very long to update which is very frustating to the user.

Actual Behavior

It should run very fast while updating

This is a perpetual issue for me as well. I'm shocked there aren't more people complaining about this, which makes me wonder if checkForUpdate is the wrong way to do be setting this up.

It seems like codepush is doing an entire comparison rather than a quick simple check. Or maybe caching isn't working right on the codepush end. I'm going to test more.

This issue is making the tool virtually unusable as it needs to wait between 3 and 20 seconds each time the app is reopened. If I can't find a solution, I may try to implement a local solution to only check once a week or so to try to avoid this issue. Or I may need to switch to a different service.

We have been facing similar slowness while checking for updates today as well on both Android and iOS. Seems to be random and roughly lasted for 2 hours around 3 PM UK time. Speed seems to drop randomly every now and then.
