Hi,
I noticed (*os.File).ReadFrom has supported splice(2) since go/1.21, and
I'm trying to introduce it to my project. But the performance is not as
expected, which is slower than the normal io.Copy (buffer size = 1MB). Does
anyone who knows the reason?
For using splice(2), I tweaked the param
side.

There is a runtime.SetFinalizer function.

You may try to use `go tool compile -S ` and read the assemble
codes to find the truth.

We detected this problem once again, and this time we observed the stacks.
See https://github.com/golang/go/issues/40372 for the details.

And maybe the reuse mechanism (e.g. sync.Pool) is good for you.

Hello!
Just quote the document:

space-separated values into successive arguments as determined by the format
Instead, you can use fmt.Scanln.

Hi!
We have a go program (an api server) on a virtual machine(with 8 cores)
with a long time stable running.
However, the program recently suffered a weird problem that only a single
CPU reached 100%
usage while others were very low, in the meanwhile, the network bandwidth
was totally zero,

This is a known deficiency of Go's escape analysis, which is recorded in
this doc:

Hello!
It's my own understanding and it's not necessary true.
The mcache belongs to per P, but by assigning it to M, we can mark M is
binded to this P.

Hello!
Recently I read some go source code and when I read the noescape function
in runtime/stubs.go, I have a doubt about it.
// noescape hides a pointer from escape analysis. noescape is
// the identity function but escape analysis doesn't think the
// output depends on the input. noescape i
