I'd also create the best indexes while re-working the code.
#Events indexes:
1) Unique Clustered on ( ProcessDate, L4Ident ) --in that order
2) Nonclustered on ( L4Ident )
3) NNonclustered on ( LinkRL4, L4Ident ) Include ( ProcessDate ) --yes, processdate would be auto-included anyway, but I like to explicitly specify it anyway, in case the clus index changes later.
