Hi!
Can i get some help in trying to improve the performance of the
following snippet?
The following code runs inside a react block that it's waiting for
channel values.
The promise $yenc_promise returns a CStruct with a CArray[uint] $data
and a uint8 $data_size.
my Instant $init = DateTime.now

Not absolutely sure, but it seems like you are copying the data twice.
Try just
my $bindata = Blob.new($ed.data[^$ed.data_size]);
Thanks for the answer.
There's a slight performance improvement, but It still takes more than 1 second:
Code:
my Instant $init3 = DateTime.now().Instant;
#my Blob $bindata = Blob[uint8].new(@data);
my Blob $bindata = Blob[uint8].new($ed.data[^$ed.data_size]);
say "Bindata in {DateTime.now.Instan
On my MacBook, with Raku 2020.01 built on MoarVM version 2020.01.1
changing:
$ed.data[^$ed.data_size]
to:
$ed.data.head($ed.data_size)
cut the time in half.
I cannot speak to what might be happening with the Promises.
Test code:
class Foo {
has @.data = 0 xx (1024 ** 2
> my Data $ed = await $yenc_promise;
The promise must initialize each element of the CArray[uint]. It looks
pretty quick; I'm guessing it's low-level code doing that.

Afaict that's a total of five
