The program is too large to post here. I have tested it with go race and it
doesn't run into any problem. Any idea of what to look for?
Thank you!

I tried with the stripped tmp version of "go run" and after a while I was
able to reproduce it too. It definitely took me more time but probably is
just random.
I tried "$ GODEBUG=asyncpreemptoff=1 ./test" and I kept seeing the the
calls every 10ms. Is this expected to happen?
I compiled the
=LinuxMint
DISTRIB_RELEASE=19.3
The 100% CPU spikes would sart at any moment and would usually stop after a
I made a new http request to the server.

Hi Brian, thanks for your help.
Al my go downloads are from go.dev
In this tests I am using
$ go version
go version go1.18 linux/amd64
I run the tests in a laptop with linux as the main OS, no emulation.
$ grep "model" /proc/cpuinfo | sort | uniq -c
12 model: 165

Hi,
On Linux, if I compile and run this simple program:
package main
import (
"fmt"
"net/http"
"time"
)
type x struct{}
func (x) ServeHTTP(w http.ResponseWriter, r *http.Request) {
w.Write([]byte(""))
}
func main() {
sp := {
ReadHeaderTimeout: 5 *
cel the request after the certain time

Using the http package, timeouts are defined per server. Is there any way
of changing it for a specific handler? Imagine a long download from a loged
user or a websocket but also be protected against clients that don't close
connections and fload the server.
