Hmmm, interesting. I made a slight mod:
# Timing test: Unicon vs.
Icon
procedure main()
local L, L2, x
t1 := &time
L := []
every 1 to 100000 do put(L, ?0)
L2 := []
every x := !L do put(L2, x^2)
t2 := &time
write("time: ",t2-t1)
end
And ran it under Linux (Redhat 9):
Icon:
time: 120
baz 0.12s user 0.01s system 97% cpu 0.133 total
Unicon:
time: 120
baz 0.13s user 0.01s system 104% cpu 0.133 total
Which seems to indicate that they are comparable speed!
(Which is what I'd expect, they should be producing
nearly identical ucode...)
Wonder what's special about the Sun machine? Might different
compilers have been used to build the two?
