I also have 16GB memory and I can see that 0 swap is used. I also
verified that rosegarden was writing to disk by using iotop.

Rosegarden 20.06 has a bug where it takes a long time to open a

I didn't test against anything recent (the newest old build I had was
from 2017), but vintage Rosegarden opened my 549-segment file in 4
seconds, while current SVN takes 48 seconds.
Running a debug build makes it clear that a lot of grinding takes place
in CompositionMapper and SegmentMapper. A release build only gets the
time down to 44 seconds. It's still really boggy.
Likewise, there's a slew of CompositionMapper and SegmentMapper calls
when copying the entire composition and pasting a copy.
I'm not noticing any disk involvement. I have 16 GB of RAM, and the disk
writes you're experiencing might be explained by swap activity.
This is confirmed, so I'm going to take the liberty of opening a bug
report for Ted to keep track of it.
