The interesting bit is what happens inside arc_reclaim_needed(),
that is, how it arrives at the conclusion that there is memory pressure.
Maybe we could trace arg0, which gives the location where
we have left the function. This
if a bug fixed in Illumos is never reported to Oracle by a customer,
it would likely never get fixed in Solaris either

I would have liked to think that there was some good-will between the ex- and
current-members of the zfs team, in the sense that the people who created zfs

Ok. I blew it. I didn't add enough information. Here's some more detail:
Disk array is a RAMSAN array, with RAID6 and 8K stripes. I'm measuring
performance with the results of the bonnie++ output and comparing with with
the the zpool iostat output. It's with the zpool iostat I'm not seeing a
lot

what is zpool zpool status
are you using the default 128k stripsize for zpool
is your server x86 ? or sparc t3 , how many socket?
IMHO, t3 for oracle need careful tuning
since many oracle ops need fast single thread cpu

one still does not understand your setup
1 what is hba in T3-2
2 did u setup raid6 (how) in ramsan array? or present the ssd as jbod to zpool
3 which model of RAMSAN
4 are there any other storage behind RAMSAN
5 do you set up zpool with zil and or ARC?
6 IMHO, the hybre approach to ZFS is the most

i just take look the ramsan web site
there are many whitepaper on oracle, none on ZFS

It's supposed to be

currently in status accepted and an RPE escalation pending.

Going Dell because they can provide solid HW support globally.
Are any of you using the MD1200 JBOD with head units *without* an
MD3200 in front? We are being told that the MD1200's won't daisy

Dear list,
I'm about to upgrade a zpool from 10 to 29 version, I suppose that
this upgrade will improve several performance issues that are present
on 10, however
inside that pool we have several zfs filesystems all of them are
version 1 my first question is is there a problem with performance
