Cannot reproduce Template editor slow performance in Safari.

[Liam W]

Affected version

2.0.2

The template editor is barely usable in Safari on macOS (macOS 10.13.3, Safari 11.0.3).

(Also, when scrolling the template editor, my MacBook makes a strange squeaking noise. I've got it on video, so I'm definitely not imagining it...)

 

[Chris D]

Certainly not disbelieving you about the squeaking or anything else but I cannot reproduce this. I've opened some of the largest templates we have using macOS 10.13.4 and Safari 11.1 and it performs just as well as other browsers. That suggests there may be some sort of localised issue.

Safari 11.1

Unless it's a Safari bug and was fixed in this version? Where can I download 11.1?

Chris is using the public beta of macOS but you can download either the beta of 11.1 or the Safari Technology Preview off that page. The STP will be kept up to date by Software Update once you've installed it

@DragonByte Tech thanks, I'm downloading the beta now. I like to wait for a few to be released for Mac before I update

Just to assure me of my own sanity, can other people hear the squeaking when I scroll?

@Liam W you have no idea how hard it is to resist saying "no" just to mess with you

Does your Mac have a spinner drive? It sounds very much like a HDD spinning sound to me.

No, it’s a 2015 MacBook. All SSD

Incidentally, the next release does include a CodeMirror update, but the change logs don't suggest that anything like this has been fixed.

Did you accidentally stuff a hamster in there that is allergic to syntax highlighting?

@Liam W do you have a video which demonstrates the poor performance? @DragonByte Tech can you reproduce any of this (particularly the poor performance)?

 

[DragonByte Tech]

@Chris D there are performance issues to be sure: https://www.dropbox.com/s/5eucz8enfzqa6pg/safari-performance.mov?dl=0

As you can see the rest of the page scrolled fine, but the editor itself runs at about 10 FPS.

That video above does actually show the poor performance, it's more obvious if I compare it to Chrome (scrolling is fast and instant).

I just upgraded to the 10.13.4 beta (with Safari 11.1), and the performance issues are still there. There are no issues in Chrome.

Off topic but I hope it releases soon, I have way too many iDevices that could benefit from Messages in iCloud But I've had way too much grief with betas in the past that I'm fighting the desire to install the betas

Back on topic, I tested this in Safari Technology Preview (latest) as well, same performance issue.

IMO if there is any performance difference, it seems negligible in my testing, and I can't particularly see anything in either video that equates to "barely usable".

It gets worse as it's used, to the point where it takes several seconds to scroll a few lines in the editor. That's definitely barely usable.
