Performance issues in Phonegap iOS game after Ads + Flurry integration

Question

I am developing a game using PhoneGap iOS. I integrated Ads in it using Mobclix as well as iAds. Also I integrated Flurry in the game for analytics.

But after integrating Ads in the game I am facing some performance issues in the game on some devices. They are as follows :-

Ipod touch :- Slow response to touch events, Animations are too slow, Rendering has become slow. Iphone :- Animations are slow but better than Ipod touch.

It works fine on Ipad.

I have used PhoneGap to port our HTML5 code on the devices.

I checked Removing the Ads and Flurry Code then game runs Fine. I also searched extensively for this problem, but couldn't find a suitable answer. Looking forward to getting some help, here.

I've noticed (from first hand experience) that the Flurry HTML5 SDK can slow your app down, massively. It communicates with the server by inserting SCRIPT tags into the HEAD section of the DOM, which has three drawbacks that I can see:

1. Some browsers (e.g. mobile Safari on iOS it seems) will wait for HEAD scripts to resolve before running any other scripts
2. If you make multiple Flurry calls, you'll soon reach the browser's concurrency limit for multiple downloads from the same server, since each call creates a new SCRIPT tag.
3. The script tags are never removed, so the DOM keeps growing.

One solution is to try the native Flurry SDK for the phone(s) you are targeting, but that's not an option if you are supporting browser WebApps, and increases your development time & download size for native apps.

I find it pretty shocking that the Flurry HTML5 SDK is so inefficient. Back to Google Analytics I guess.
