Ultimaker Original slow printing

[Robavh 0]

I rescued an old Original, and tried to print. After some attempts I succeeded, but the print is very slow. When I looked at the Gcode, I found various commands with a speedrate.

row 29, 34, 39, 41, and 42 contain speedrates , with F600 as the last one before printing. Why so many without effect?

Then, at row 110 through 117 this occurs again, but now with a lot of G0 codes which don't take any effect as well. Why?

How can I make the printing faster?

I hope someone can help.
