Bug Description

Version: Ubuntu 14.10 r17

Reproduce:
- open settings app
- scroll down and click on "About this phone"
- click on "Storage"

Result:
UI gets frozen for about 6sec before "Storage" page appears on the screen.

Expectation:
"Storage" page to open instantly.

<https://wiki.ubuntu.com/AboutThisDevice#storage>:
“While all the sizes are being calculated:
 * the chart should be an indeterminate progress bar, exactly the same width and height as the eventual chart;
 * the value for ‘Free space’ should be ‘Calculating…’;
 * the value for all the other categories should be ‘…’ (to minimize repetition);
 * the list of apps+scopes should not be present at all.”

Thanks, indeed that page could be optimized. What device are you using?

This isn't a UX issue but a performance issue, the expected UX behaviour is for storage to load within half a second!

Reproduced on Ubuntu 15.04 r91 on an Aquaris E4.5. Immediately after restarting the phone, in five trials, opening the "Storage" screen took 11 seconds, 10 seconds, 10 seconds, 10 seconds, and 10 seconds.

If two seconds with nothing changing on-screen is long enough for you to start worrying whether something is wrong, then the "worry duration" here is 10 seconds – 2 seconds = 8 seconds. For a GUI, that's extremely long.

Fixing bug 1488005 would greatly lessen this bug, as well as most other responsiveness problems in System Settings. In this case it would halve the worry duration: 10 seconds – 2 seconds of highlighting the "Storage" item – 2 seconds showing a skeleton screen – the first 2 seconds that the spinner was visible = 4 seconds. So I strongly encourage fixing that bug.

But a worry duration of 4 seconds is still 4 seconds too long, and that can't be eliminated by designer fiat. Calculating storage usage, on current filesystems, is one of those things that just takes a long time. Other systems deal with this by having custom placeholders on their equivalent screens during the calculation.

Unless there's some magic we can perform that those other systems can't, we'll need to do the same.

@jgdx
We should do a few things to make this better:
1) display the page immediately and perform whatever necessary operations for the calculations async
2) display results as they come in on the page, showing spinner (or whatever spec'd by design) until the page is fully loaded
