This looks funny, it seems that RDI is never modified by the loop (?) so lines 18-24 always load the same data, presumably from L1. It's mysterious why of all those instructions, 20 and 24 get most interrupt hits.

Good observation about rdi and its implications for the load of rcx (line 18) and therefore the load through rcx (line 20).

I added a note to that effect and also enabled adding comments to the spreadsheet.
