Long pauses browsing meta on android galaxy s3

Is there any tool that I could use to give some more useful information about this? The writing dialog gived me the most annoying pauses.

This is a very old phone, released in 2012… you can expect performance to be quite poor.

Android unfortunately is very slow in Discourse, due to limitations in Chrome’s JavaScript engine. Even on a fast device it is only so-so. Use the latest Chrome and it is a little bit faster.

The typing dialog aka. composer is actually the easiest thing to address, if there are pauses we should be able to address them, not much needs to run on every keypress on mobile.

Are you talking about the composer here?


(Fábio Machado De Oliveira) #4

I think it is related to the autosaving in the composer. Its possible that
waiting more or disabling autosaving for weaker phones could help a lot.

I had some pauses on scrolling too, that if there is any tool you use to
profile this I would like to try identifying what is causing them.

Are midrange new phones like the moto-g supported? Do they perform better
than the S3?


(Rafael dos Santos Silva) #5

A mid range like the Moto X Play, 1.2k in Brasil, will be way more powerful than the S3.

@sam’s ember 1.8.0 complex list test results on my S3, how bad is it?

Results (1.8.0-beta.5)
Name # Runs Geometric Mean Mean Std. Dev Max
Complex List 40 1793.12ms 1828.25ms 476.79ms 4660ms

link I used: Ember Performance Suite

I didn’t let the phone turn the screen off, that would probably change the
results.

In my experience, the limiting factor is RAM. My 1GB Moto G will run out of memory and quit the Chrome process while I’m in the Gallery picking a file to upload, thus making uploading impossible. On Android, I’d recommend 2GB as a minimum requirement.

So that number means your phone has roughly the performance of the 2011 iPhone 4. For perspective, the iPhone 6s is literally ten times faster in real world stuff. 10x.

It improved a lot in today’s new version (or my ISP was misbehaving)
