App is a bit slow. Can it be optimised?

[TheRealMystic]

Both my phones are quite powerful, with one running on Snapdragon 8 Gen 1 and the other running on Snapdragon 865. Yet, the app takes a few seconds (usually between 3 to 5 seconds) to load all the info when launching it, when using filters, sorting, refreshing, etc.

Can it be optimised to make it Superfast, i.e. less than 1 second?

[d4rken]

I'll check, reading the whole app list multiple ways is costly. Especially reading it with different flags to find those extra apps in work profiles is also costing us time.

Super fast on first launch will require on-disk caching.
Possible to first use the cached data if not too old, while in the background loading new data.
Quite some work, something for the future?

Depending on how fast the storage is, it may not be faster on every device 🤔.

Most devices are now UFS 3.0 and above. They are quite fast. Even those with UFS 2.x should be fast enough for this purpose.

UFS3.0 are just labels, real world looks different.
Also if users do something like add extra sdcard and adopt as internal storage, it could be super slow.

Yup, those are just labels.
I did adopt my sd card as internal storage and kinda slow

And also, reducing the life of nand flash/sd cards

Internet Security companies found a new way to improve the speeds of their antivirus scans. They implemented things in a way that can track all changes since the last scan, and the next scan would only scan those changes. This made the antivirus scans real fast and also placed lesser load on resources.

Can something along those line be implemented in PP? This will make all operations real fast.

PC is more faster than android, even a budget pc will be still faster than android.

Also this:

Not every person on earth uses new phone/old phone with fast storage

Phones are quite fast these days.

Even budget phones today have good speeds for normal functions. There is a target API and minimum API for apps. So a compromise has to be made in terms of supporting very old devices.

For this app to monitor all changes, it would have to be constantly running, which would use some processing power, albeit not much, as well as battery, which may be a bigger issue. Neither of these are issues with AV on PCs. A better method may be using snapshots, to quickly see what changes were made since last time, effectively doing the same thing as constant monitoring, but that would likely take some time and result in little if any noticeable improvement. I'd think it would be easier to speed up filtering, etc, which is also something you're likely to do a lot more, than startup, which probably isn't something you're going to be doing that often, certainly not so much that a few seconds is a big deal. Really, though, I'm impressed with how fast it is for how much data it has to look through. Startup only takes probably 3-4 seconds and filtering is either instant or takes maybe a couple seconds, and I have a lower-end processor than you. So maybe there's something else going on. Maybe you have a lot more apps?
