Hey,
I'm running windows cli exe on linux via wine using os.Exec command.. this
takes 28s to complete.
If I run the same command via linux cli it takes 2s to complete, if I run
the same command via php's exec it also takes about 2 seconds to complete.
== linux cli ==
time WINEDEBUG=err-all,fixme-all WINEARCH=win32 /opt/wine-staging/bin/wine
cmd.exe /c help
....
real 0m1,366s
user 0m0,002s
sys 0m0,225s
== php ==
cat t.php
<?php
$out=array();
exec('WINEDEBUG=err-all,fixme-all WINEARCH=win32 /opt/wine-staging/bin/wine
cmd.exe /c help', $out);
var_dump($out);
.....
real 0m1,427s
user 0m0,035s
sys 0m0,216s
==go exec==
func main() {
now := time.Now()
ctx, cancel := context.WithTimeout(context.Background(),
120*time.Second)
defer cancel()
cmd := exec.CommandContext(ctx, "/opt/wine-staging/bin/wine", "cmd",
"/c", "help")
cmd.Env = []string{"WINEDEBUG=err-all,fixme-all", "WINEARCH=win32"}
output, err := cmd.CombinedOutput()
if err != nil {
fmt.Println(err)
}
fmt.Println(string(output))
fmt.Println(time.Now().Sub(now))
}
time bin/osexec
real 0m39,915s
user 0m17,062s
sys 0m0,195s
* I have tried to set stdin and std out directly to the one from os (no
difference)
* I have replaced cmd.CombinedOutput with cmd.Run() (no difference)
go version
go version go1.13.3 linux/amd64
I'm totally clueless on what's going on.
BR,
Miha
