I am using apache cordova 1.6 for my BlackBerry application. When I open the application on my BlackBerry Torch 9810, it keeps showing the application load screen for 7 to 8 minutes. After a long wait it goes to the first screen. When I deploy a normal cordova application it hardly takes 1 minute to open. Can anyone help me find the solution to my problem?
My application is 5.9 MB big and I'm using BlackBerry OS 6.
There could be various reasons why an application takes longer to open. But, you can narrow it down by using the profiler. Here is another thread which discuss about the same topic and a solution had been proposed at the end of the thread.

We've created an webview style hybrid app, using framework based on PHP
Compared to Android, it takes twice as much time to load the app on the iphone
We've packaged the app using wk webview which based on Safari.
Is there any issue that we can check in order to solve such slow running problem on iphone?
Best regards
General question. I'm developing an app using React Native, and certain actions bring my app up to around 500MB of RAM, where it usually gets killed.
I've searched the web for good material on RN memory profiling but have found nothing. I've tried using Instruments, but it's output doesn't give me much insight as to what are my memory guzzling processes.
TL;DR: Do you have a good way of profiling memory usage in React Native?
P.S. currently focusing on iOS.
Thanks in advance!

If you shake the device you can bring up the debug menu and enable perf.
Additionally if you're on iOS, xcode comes with a set of performance tools. In spotlight, cmd + space, search for instruments, open it and select Activity Monitor.
Performance
App developer menu - toggle Show Perf Monitor
You can use Xcode and Android studio for this case.
On Xcode, you can check below screenshot.
Also for the Android Studio, you can open profiler on 'View->Tool Windows->Profiler'
We are working on a PhoneGap2.9 application for BlackBerry 6,7 and 10 and we are testing it on Curve 9220 with OS 7.1 and it is taking 25 minutes to put the application onto device using "BlackBerry Desktop Manager" and this whole process it time consuming
We would like to know if there are any better ways to do it
any suggestions would be highly appreciated

I read an article recently which states that web apps on iOS launched from the home screen running in full screen mode have slower performance than webapps running inside safari.
Then I found a followup article to it which seems to sugguest that the issue above is fixed.
Does anyone know if this is confirmed?
According to information from appleinsider, ios5 beta fixes that problem and now Nitro JavaScript engine enabled on Web.app.
I've iOS 5 installed on my iphone4 and updated SunSpider JavaScript testing framework 0.9.1 (to be able to start as fullscreen web application under ios). And I've started subspider several times in fullscreen webapp mode and in Safari mobile. So, see my results below (images are clickable):
May be something was fixed (apple insider provides 4 vs 10 seconds difference), but I can't say that performance is equals in both cases (3756.5ms vs 5243.8ms for those who can't see images).
UPD
Small interesting note about UIWebView, it is impossible to use Nitro-enabled JavaScript engine in native applications (I mean applications designed in Xcode and posted to AppStore) because Nitro JIT requires to be able to use dynamic code signing.
UPD
Look at iOS 5 Top 10 Browser Performance Changes on blaze.io, Seems Apple enabled Nitro for Fullscreen WebApps in iOS5 (nice statistics in article).
I m working on Blackberry development when i click debug in the JDE my simulator takes long time to load the program and my desktop configuration are current configuration with 3GHZ processor and 4GB ram . I don't know why this happening ?
From the official BlackBerry Developer Blog, here is a new post on setting up the simulator to boot as fast as possible.
How-to Set up a Lightning Fast BlackBerry Smartphone Simulator
It's not an exact solution to this question as it doesn't specifically speed up the attaching of the debugger, but it should help with simulator startup time.
