As you can see the expression p^ is only evaluated once in the TestWith
case while it's evaluated twice in the TestWithout one. So it's only
minimally faster in this example (one less memory access), but if you
use enough members of TTest

We all know Lazarus is way better that Delphi - so that's always good to

Hi All,
If my application needs SPEED, i.e. take full advantage of CPU
