Hi all,

I am having load time issues with my app that I am writing. The problem is that on a device or emulator, the app will take about 45 seconds to load, but only about 2 of that is loading my app. The rest of the time appears to be things going on in the OS. Please forgive the length of my post, but I'm not sure what is relavant to the solution. If anyone has any insight, that would be amazing.

Here is the debug log. Everything related to my app is in bold.

[simon_hain]

what does your app do?

[heather_1]

The app is a business directory. While loading, it checks a server for updates, and if there are any, parses them and puts them in a database.

[simon_hain]

do you use a separate thread for blocking operations, like network or database I/O?
If not, do so.

[heather_1]

I am using a separate thread for all the network operations. The only thing on the main thread is the splashscreen.

[MSohm]

The best way to determine what is causing the delay is to use the BlackBerry Profile view in Eclipse (it also exists in the legacy BlackBerry JDE if you are still using it).  

To use it set a break point at the start of your application and another that would be hit after your splash screen has been hit.  Once stopped at the first break point, click on the Window menu of Eclipse and choose Show View -> Other.  Then in the window that appears expand BlackBerry and choose BlackBerry Profiler View.  Then continue on to your next break point.  This will show you the number and percentage of CPU cycles used by each method that was called.
