What I meant is severe slowdown when reading variables that are

It happens for both AMD and Intel on both Windows and Linux.
Spacing such variables farther apart has dramatic impact but
is quite inconvenient in most cases.
IIRC I once read a recommendation to group shared variables in
(larger) structs. With structs you have control over their memory
spacing and improve cache behaviour.
