I don't want to offend any of you Jolla employees out there, you're doing an tremendous work.

Anyhow, when the latest update was released, it was said that it would speed up the phone to be more smooth and enjoyable than ever before. App startup time was said to be reduced and scrolling speed of home screen improved.

Unfortunately I am not experiencing any of these improvements. As the matter of fact, I feel that my phone has become slower since the last update. Therefore I'm a bit surprised when I read all the praises about how fast the phone was going to be after the update.

Am I the only one feeling this way, or do you also not feel the improvements that was promised with latest update? Should I re-install my phone and hope for the best?

Also i feel app animation is not required in cases where it can be opened almost immediately. That seems to give tad slow feel when opening apps. Earlier phone, messages apps used to open faster than noe

You are not alone. I can't see significant improvement in app loading time.

For me it's the same. Especially when installing updates in Warehouse, it is extremely slow and I get constantly "Warehouse is not responding" popups.

They've improved or replaced the renderer, from what I recall. So transitions look smoother, and there are massively fewer and less severe frame drops (implemented a frame buffer?). The previous stutter fest is gone. However, presumably this and the many accommodations for the increased memory usage under Qt5.2 seem to have made the OS generally slower. Load / thinking times are significantly longer than under update 9 (or update 8) and the phone does feel quite a bit slower, albeit smoother with it.

I'm actually experiencing much worse out of memory problems under update 10 than 9, too ... or at least it seems to be infinitely easier to trigger the out of memory app killer that closes everything except the phone app. It happens all the time, particularly when using a browser.

The phone was never fast or smooth, despite what some people will tell you. It's less fast than it was, but it is relatively smooth now. I'm sure most people will prefer the lack of stutter, and I would too if I had any control over the OOM App Killer (or it at least gave me a warning) ... but as it currently stands, I'd take the stutter any day.

My biggest worry is that in their effort to try to mitigate the memory and resource issues generally, they may be gimping performance on more powerful hardware in the future. Hopefully that's not the case though.

I experienced the same issue of all apps being closed relatively often after upgrading from update 9 to 10. This was, for me, resolved by a factory reset. Since then I've not (yet) seen the issue return although I rarely open more than 4 apps at a time.

Look in this discussion for hints by @tigeli on how to change OOM killer parameters:

https://together.jolla.com/question/72016/browser-and-oom-handling-with-update-10/

It's too technical for me, maybe it helps you. I do hope there will be an easy setting slider for this, or Jolla to simply improve the settings in the next update. This OOM-killer really kills the multitasking experience, which is supposedly one of the usp's of Sailfish.

The primary problem right now is memory usage. Native sailfish apps surprisingly consume quite a bit of RAM, for example a simple hello world app built from the SDK template already uses up more than 40 MB. u10 actually includes an attempt to improve the situation by utilizing zram, but it is suboptimal (see https://together.jolla.com/question/75162/replacing-zram-with-zswap/ for details).
