Does SUMPRODUCT slow down Excel?

One blanket statement about SUMPRODUCT can be said: the use of entire-column ranges (e.g. A:A) that Excel 2007 and later permits with SUMPRODUCT probably unduly slows down calculations because SUMPRODUCT must process usually multiple instances of arrays of 1+ million elements.

Which is faster index match or Sumifs?

From a purely speed perspective LOOKUP and INDEX-MATCH (type 1) are the fastest, followed by INDEX-MATCH (type 0), with SUMIFS the slowest as it is required to scan the entire criteria range whilst the other functions stop once they find a match.
