Follow-up Comment #2, bug #47090 (project pspp):

Running the following syntax:

input program.
vector vec(2500).
loop #v = 1 to 2500.
 compute vec(#v) = #v.
end loop.
end case.
end file.
end input program.

descriptives all.


takes:

without a gui:       0.3 seconds
with 0.8.5 gui:       11 seconds
with master HEAD gui:  3 minutes
with a special hacked up gui using the efficient-sheet I'm working on: < 0.5
seconds

I wonder what we've done since 0.8.5 to make it so slow?
