However, I noticed a minor degradation in performance after this change, from ~41 c/s to ~39 c/s for a non-OpenMP build. This change is not huge, but can be observed consistently.

The above is unclear: have you increased the size of the array (along
with switching to dynamic allocation) even in non-OpenMP builds?  Or has
the size remained the same, yet performance degraded?
