Hi,
We are currently working on a project where we cache all screens on
start-up, by using
Qt.createComponent(url). By this the major components are parsed and
cached on start-up. It has also a second benefit, it verifies your
components on syntax error on start-up.
For my knowledge the Loader element will try to load the component later
and will hit the cache (as the URL is the same).
Actually we go even a step further to create a large registry of all
application screens so we can call the screens by the registered name
and not the component url.

Hi all,
I have an application written with Qt 5.2 in C++ and QtQuick2, running
on a low-end ARM device. I use the Loader item to select between
various screens in the application (I've currently got 6 screens or
so). This way I can limit the amount of active bindings at a given
time, etc.
The first time I enter a new screen, there is a very noticeable delay
(1-2 seconds), as the new items are "compiled". The next time I enter
the same screen, the delay is much shorter. So I guess some things
have been cached in memory.
Would it be possible to cache this on disk, to prevent this from
happening every single time the application is started? I'm asking for
something pretty similar to Python's ".pyc" files.
Is it possible, or would it be possible in some future version of Qt?
Cheers,
Ola
