GoDaddy VPS Server Speed & Optimisation Required for iOS App. *URGENT*

We currently have two servers, a test server and a VPS Server with Godaddy. Our iOS app is working perfectly with the test server and working fast, however on the VPS Server it is not working fast and is giving multiple errors. There are no issues with the speed of the code. Our server is CentOS 6 Only. We require someone to optimize the GoDaddy VPS Server to ensure there are no delays and no lags. You will be expected to provide proof of changing the speed. You will need 2 iphones to test 2 IPA’s which will be given. The IPA on the GoDaddy VPS server needs to run just as fast if not faster than the IPA on the test server. One of the main issues we are having is with things such as pictures taking very long to load. You will need to provide your UDID number to be able to test the IPA’s on your devices only. Any errors or lags should be clearly shown through a screen capture if not resolved. You will be paid once the app is fully optimized on the new VPS Server, there are no delays and everything is working perfectly including the payment gateway. Please note, we have two domains which are also hosted out of the GoDaddy VPS Server which should not be affected. WE NEED TO AWARD PROJECT TODAY. PLEASE BID URGENTLY.
