I saw something about that just recently ... can't remember what all
was said but basically it was about just what you mentioned in some
sort of busy .. maybe .. college or commercial setting where users
were groaning about poor performance and some sysadmins got together
and and setup some means ofboosting that issue... was that were you
are?

When you say SSD or better.  What kind of setup is better than SSD?
Maybe like in the cpu itself.  Better buffering or such.

What did living with it consist of... I get you mean waiting on
something. Where do you feel it at.

All I do with zfs is dink around with it... I have no computing life
other than just tinkering ... no job related stuff or comercial
headaches to worry with.  But I'm curiouis to know where a serious
user is put out by bad zfs performance.

I've run zfs for several years but always just hobbying.  I ran
openindian now called openindiana/hipster in fact I was running it
when that hipster thing started.

One of the big things that impressed me when I first started with it
was the ease with which it uses disks.   I've stuck some pretty
raunchy old drives in what was my zfs machine back then and zfs just
went to work on them.  No formatting issues or the like.

I would have stayed right with openiniana but it got to where I was
having lots of trouble with install media.

I saw that ubuntu had a zfs choice that happened during install and
jumped on that..  I'm back tinkering with openindiana/hipster now.

OOPs sorry about wandering off there.
