[Kmymoney-devel] Startup is slow

[Thomas Baumgart]

Hi,

sorry for the delay in answering. I do filter all MS-Windows related mails to 
a separate queue and look into them only every now and then.

Cool.

And I am sure we can guide you through it. You should probably make sure that

- you are subscribed to this list (the devs main communication channel)
- use "git master" source code and clone the repo 
(git://anongit.kde.org/kmymoney.git) if you have not done already
- post your patches to https://git.reviewboard.kde.org for review
- remind us if you don't get an answer within a few days.

Unfortunately, I have not used MSVC in ages and also not with KDE code, so I 
won't be of much help if it comes to details how to do debugging there. I 
wonder though, that it is not possible to single step through the code and 
look at some variables, or did I misunderstood your comment above?). A couple 
of things which I can thing of:

- Make sure to build with CMAKE_BUILD_TYPE=Debugfull which gives you new menu 
options at runtime:
  - 'Tools/Debug Timers'. You can then add call to the ::timestamp() function 
(in main.cpp) in the code to get timing values on stdout (shell window).
  - "File/File information" showing details about your data. Can you post a 
screenshot of that information here to let us know something about the number 
of items in your file? (I attach mine here for reference)

  It might also provide you access to variable values

- If you have questions please ask here


One thing that crosses my mind regarding the startup process is that you can 
reduce the amount of information shown on the home page using the settings 
dialog. This probably also helps to identify which part of the code causes the 
most delay.

Again, sorry for the delay which is certainly not the normal situation.
