It is a good idea. I will use this method.

    require Win32::Process;
    import Win32::Process qw(NORMAL_PRIORITY_CLASS);
    my $flags = NORMAL_PRIORITY_CLASS();
    
    # Create and execute a process to start
    my $ProcessObj;

    Win32::Process::Create( $ProcessObj, $executable, $argument, 0,
$flags, '.' )
      or die Win32::FormatMessage( Win32::GetLastError() );

Thank you.
