The question is why this change actually improves performance - we need to understand that, so we can tell whether we also need to look at other structures and see if there are problems with them. The question at the moment is whether this is a variable alignment issue (which would be surprising, as the x86_64 ABI specifies that all pointers should be aligned on 8 byte boundaries), or something more subtle, possibly related to cache line usage. The other possibility is that this is something entirely coincidental, not related to your code change at all. Further investigation is required.
