with the Rebol/Base:
system/stats/series
;== [4096 2624 1353 1 118 117 70]
t: now/time/precise loop 100000 [make block! []] now/time/precise - t
;== 0:00:00.1
system/stats/series
;== [66048 13825 1199 1 51023 51022 75]
foreach pool system/stats/pools [probe pool]
...
(using new Rebol/Base console)
system/stats/series
;== [4096 2624 1353 1 118 117 70]
t: now/time/precise loop 100000 [copy []] now/time/precise - t
;== 0:00:00.09
system/stats/series
;== [66048 13822 1199 1 51026 51025 75]
foreach pool system/stats/pools [probe pool]
...
So it looks that there is almost no difference between the copy [] and
make block! []
The other issue would be with the make block! 10 which allocates more
memory.
