/OT
there's an old saying, numbers don't lie, only _____.
[you can fill the _____ with whatever, I like 'salesperson']
update: ____ should be wall-street-analysts
/OT/

there are too many tunables, and I really don't want to spend all my waking
hours tunning, but once in a while, I do check performance, and running
top, iostat, nfsstat, etc, sometimes show a 'congestion'.
the problem I encounter very often, is that what is a great solution for one,
might be disastrous for another.

ZFS is the new kid in town, and so far I am quiet happy - have 2 in production,
and the new one will be very soon, it's being used to train/learn/play but will
go online very soon, then it will be hammered by several projects, and it
would-be-nice to have some tool to watch performance and be able to do some
tunning, to quote tunefs:
	'You can tune a file system, but you cannot tune a fish.'
