Why does this function run so much faster when it makes an extra read of memory?

I'm currently trying to understand the performance properties of certain loops on x86_64 (specifically, my Intel(R) Core(TM) i3-8145U CPU @ 2.10GHz processor). Specifically, adding an extra instruction to read memory inside the body of the loop almost doubles the performance, with the details not being particularly important. I've been using [...] read more
