True, although commas work too ...

You want performance tuning suggestions, is there a particular problem you are trying to solve or do you just want it to "go faster"? if so, is there any more bandwidth available on the machine? Also, I note you want it to go fast but you don't appear to care if it all goes wrong : > TAPEDEV /dev/null # Tape device path> > > LTAPEDEV /dev/null # Log tape device path> so no archives and no transaction logging?
