Investigate Memory Limits on iOS

Ok. As we said in issue 279, the crashes can be caused by a memory limit.
So first you need to test the extension with various amounts of scripts, to see if at a certain point it crashes and reproduces the exact error message.
Eventually, a method to limit the number or size of the js files loaded by the extension should be devised.
If instead the error does not relate to the memory limit, further investigation is needed. I can provide you my scripts to test them.

@Emasoft

if you want to send me your scripts, my email is on my profile page, I hope to be able to investigate this on the weekend

I did some profiling this weekend and found some areas that could benefit from optimization, i think a lot of it revolves around #278, but also code level improvements that should be investigated around the parse function being used

I was using ~64 userscripts some quite small in footprint and others quite large

I have nothing specific to share right now outside of that, but will update this thread as more discoveries are made

Any progress on this?
Even after the last update on iOS, the issue is still present.
The error is the same, and retry doesn't do anything 95% of the times.

I've sent you my Userscripts folder in a zip file to your email. Please test it.

@Emasoft I got your files, thanks for sending. Are you seeing this on iOS or macOS? I noticed the folder name mentions iOS but the image you pasted shows macOS. I have not yet been able to reproduce this on macOS, but I will keep trying.

Edit: For a moment I thought the screenshot was macOS, I see that is not the case now.

Can you give me you device details?

Thanks, I am testing on an iPhone 8, running 15.6.1, but have not hit the issue yet :/
