Best Performance settings for filepro

[John Esak]

Bill Vermillion is your man for this type of question... but my suggestion
is to not mess with the default stripe... even though it is 64 and I've
usuall seen 32. Someone defaulted it for a reason and just changing it will
not probably reflect in any significant or noticeable speed ups.

As for the cache... read ahead.  Again, no particular defense other than
that is what it usually is and why mess with success.
