Super! That what i was looking for, i changed the code to:
my Instant $init = DateTime.now.Instant; my Blob $blob = blob-from-carray($ed.data, size=>$ed.data_size); say "bindata = {DateTime.now.Instant-$init}"; Output: Bindata= 0.00060054 So it passed from approx 1.1 to 0.0006 secs. That's quite an improvement! Thank you so much.
