No. All databases I used in my tests have a page size of 4096

Another No.
Sorry, I forgot to mention that I ran another test with a restored
database on the "problematic" server. And it was still the 500ms

Any other idea?

If it's useful I could offer two network protocols (ethereal)?
One with the 43 columns (slow) and one with 44 columns (fast).
