This is an excellent improvement and we believe we can improve this even more in the future. The highest startup time improvements we’ve gotten are as high as 90% in the case where the application is very JavaScript intense and contains no other items, like graphics, to load at startup. I do agree that we should provide more metrics and also provide to others validate these. However the most relevant question is how much is the improvement in Your use case. Best way to check that is to try. There are, of course, many other things to optimize startup time. After these are all done, QQC still shaves some time away from the startup. Yours, -- Tuukka Harri Pasanen ha...@mpaja.com kirjoitti 14.11.2014 kello 17.09: Actually I was less interested in the compilation time than what it is the return for the investment. Reading the compiler docs, they recommend disabling the compilation for debug builds, as it can interfere with debugging. So through configure the build/deploy cycle should stay the same for debug builds. Of course in reality you will need to do a couple of rounds of testing with release builds as well. But nobody has mentioned any figures on the speed gains resulting from using the compiler. A related question, has anyone tried to coax QML, or rather the javascript components through the Closure Compiler? https://developers.google.com/speed/articles/compressing-javascript It might help a little, especially with javascript heavy QML, as it would reduce the working set size / cache misses, etc. Idle thoughts, Harri On 14/11/2014 13:24, rpzrpz...@gmail.com wrote: Then that would make the benchmarks that Harri requested a mute point. Unless you make clean, the incremental build would not care about 10,000 lines of QML code. It would only slow down on the changed QML.

Hi all. Please revert back changes from http://qt-project.org/wiki/Gerrit-Introduction page. This changes made from 11:43, 5 Nov 2014 by alkino. Earlier I used this page for direct copying of Git links examples for a contribution to the project. But now mention of port 29418 and others things are deleted there. Thus now WIKI contains invalid examples and new users will be confused. I do not understand, why this deletion was made.

Did you see the last paragraph in the Creating a new contribution section? See the step-by-step introductions below on how to complete a commit upload. Note that Gerrit SSH service is running in port 29418. There is no need to write this port number every time, just add the following lines to ~/.ssh/config file: Host codereview.qt-project.org User username Port 29418 On 11/15/2014 05:39 PM, Denis Shienkov wrote: Hi all.
