Readdirnames wasn't much better. Now using globbing and syscall.Unlink
which take ~1minute 30seconds. It is much better, but still a long way from
perl's sub-20 seconds.
package main
import (
"fmt"
"path/filepath"
"syscall"
)
func main() {
upperDirPattern := "/var/spool/directory/*"
matches, err := filepath.Glob(upperDirPattern)
if err != nil {
fmt.Println(err)
}
for _, file := range matches {
syscall.Unlink(file)
}
}
