sorting

I'm having a heck of a time trying to get a silverlight datagrid to properly sort, and do so quickly (sub 1/10 second). Here's the scenario:

-WCF callback every 1/5 of a second -Take the callback, match up to the existing record in an ObservableCollection -Update the ObservableCollection's properties -Bind the grid.

I've tried a linq query, PagedCollectionView, and observablecollection.select(), all are waaaaaaay too slow, and introduce 12+ second delays in processing. Anyone else experience this?
