Remote Object always gives the better results then http. Reason being you don't need to parse the data into the custom objects in case of remoting and transfer is in binary form.
Array collection is preferable, as you want to hold the objects and you have to make use of binding as well which is not fired in case of simple array. Now, if you want further optimization you can perform the client side paging as the no. of records are a very huge set. Implementation of paging is somewhat in RIA way rather then traditional next and back way. Hold all the 10k records in a single ArrayCollection(M). Take a seprat array collection(S) declare it bindable and provide it as a dataprovider to your datagrid. Now put first 100 records from M to S. when the user starts scrolling you will get a scroll event and position. Based on the the position add additional records from M to S. This way you can render your datagrid faster in the start-up and can give a comparatively better end user experience.
