Thanks Jochen. Lots of good information and pointers there. My SSD was actually
a G2 device. There was also newer firmware for the disk available
which I installed.

Yes, I also found that I had noatime already on.

I haven't switched home yet, so I have only programs on SSD. But I
might also use ext4 for home.

This is where the pain starts. I started looking at this and suddenly I
was up to my neck in partition boundary alignment calculations. But
I guess I finally managed to get them right. Probably wouldn't have
made a difference even if I had skipped that part.
So far so good. Bigger programs like OpenOffice and the like start
noticeably quicker, but the difference is not as big as I thought. I'll
see how the system feels once I get home transferred also.
