What you are probably noticing now is the memory test period.
When I upgraded my SE to 2.5M, I noticed the same thing. It takes a
while to check all that memory. { Several years ago (maybe even still)
the Atari ST operating system would zero out all unused memory when
it started an application. On the 512K machine, this was unnoticable.
On the 2Meg and over machines, it was intolerable. } You can bypass the
memory test on startup by holding down the mouse button at the right time.
