Hi,
compression is off.
I've checked rw-perfomance with 20 simultaneous cp and with the following...
#!/usr/bin/bash
for ((i=1; i=20; i++))
do
cp lala$i lulu$i
done
(lala1-20 are 2gb files)
...and ended up with 546mb/s. Not too bad at all.

Since you were already using filebench, you could use the
'singlestreamwrite.f' and 'singlestreamread.f' workloads (with
nthreads set to 20, iosize set to 128k) to achieve the same things.
With the latest version of filebench, you can then use the '-c'
option to compare your results in a

Are you talking about the documentation at:

or:

i was talking about the solarisinternals wiki. I can't find any

That all said - we don't have a simple dd benchmark for random
seeking.
Feel free to try out randomread.f and randomwrite.f - or combine them
into your own new workload to create a random read and write workload.

Hi again,
i did not want to compare the filebench test with the single mkfile command.
Still, i was hoping to see similar numbers in the filbench stats.
Any hints what i could do to further improve the performance?
Would a raid1 over two stripes be faster?
TIA,
Tom

Hi Thomas
the point I was making was that you'll see low performance figures
with 100 concurrent threads. If you set nthreads to something closer
to your expected load, you'll get a more accurate figure.
Also, there's a new filebench out now, see
Hi,
i checked with $nthreads=20 which will roughly represent the expected load and
these are the results:
IO Summary: 7989 ops 7914.2 ops/s, (996/979 r/w) 142.7mb/s,255us
cpu/op, 0.2ms latency
BTW, smpatch is still running and further tests will get done when the system

i wanted to test some simultanious sequential writes and wrote this little
snippet:
#!/bin/bash
for ((i=1; i=20; i++))
do
dd if=/dev/zero of=lala$i bs=128k count=32768
done
While the script was running i watched zpool iostat and measured the time
between starting and stopping of the writes
Do you have compression turned on? If so, dd'ing from /dev/zero isn't very
useful as a benchmark. (I don't recall if all-zero blocks are always detected
if checksumming is turned on, but I seem to recall that they are, even if
compression is off.)

Hi all,
i want to replace a bunch of Apple Xserves with Xraids and HFS+ (brr) by Sun
x4200 with SAS-Jbods and ZFS. The application will be the Helios UB+ fileserver
suite.
I installed the latest Solaris 10 on a x4200 with 8gig of ram and two Sun SAS
controllers, attached two sas-jbods with 8
