Alan, What are you using for backend storage? I did some minor tuning for my EVA8100 and went from 200MB/s to 550MB/s. Also, by default, plocks are set to some rediculously small number, 100 if I recall. You can rais or eliminate that limit fairly easy. That seems to help as well.
If people know more about your hardware, it'll help in finding what knob to turn. -C On Thu, Mar 4, 2010 at 2:33 PM, Alan A <[email protected]> wrote: > We are trying to deploy GFS in production, and are experiencing major > performance issues.
