[AC-6138] HTTP Request Performance

We are experiencing slow performance making basic HTTP calls through Appcelerator. This seems to affect both Android and iOS builds, however iOS does seem to be slower overall. The requests are essentially basic HTTP POST calls and all go via the same function code below:

this.sendToServer = function(params, httpParams) {
	if (Alloy.Globals.NETWORK_ENABLED) {
		var xhr = Ti.Network.createHTTPClient(params);
		xhr.validatesSecureCertificate = false;
		xhr.open('POST', this.url, true);
		xhr.send(httpParams);
	} else {
		params.onload();
	}
};

The same calls made via our web and desktop versions of the application are performing significantly better. We recently upgraded to Titanium SDK 7.4.2 & Appcelerator CLI 7.0.9. Unless there are any modifications to our code you can suggest, there seems to be a bug in the performance of the underlying requests perhaps introduced in a recent Titanium SDK change.
