I know this question has been asked for million times but after wasting hours on surfing i didnt reach on any end result. My scenario is that we are going to work on a very large project where we will be dealing with a lots of data (say millions of record of hundreds of users), so performance is really a concern on the other hand responsive design is another concern(we want our application to be globally and smoothly accessed) and again the JavaScript used in third party controls may create an issue of performance while working on a small device(like mobile)(correct me if i am wrong). Third party controls will save our time on writing lots of jQuery but i am totally confused which third party control i have to go with. Is there any one who is perfectly happy with any third party controls on such scenario.

Thanks
