<DIV><SPAN class=828593822-12052008><FONT color=#0000ff size=4>Now maybe we're
getting somewhere =). The write through is best set in BIOS. RedHat driver
*may* correctly detect that setting. The drivers "assuming" write through as
stated means that on a shutdown 0, the driver may not issue "flush the
cache" commands. If you are quick on the trigger and kill power as soon as it
says OK, and the computer gods don't like your most recent sacrafice, you can
lose some of the cache writes (with no error logged). </FONT></SPAN></DIV>

<DIV><SPAN class=828593822-12052008><FONT color=#0000ff size=4>Now as far as
identical systems - you can see that one is an Adaptec and one is a Dell
PERC (dpti) Megaraid controller.</FONT></SPAN></DIV>

<DIV><SPAN class=828593822-12052008><FONT color=#0000ff size=4>I'd bet a Big Mac
that the BIOS of the Adaptec is set differently than the PERC on write-through.
Also the controllers may have significantly different cache memories installed
and certainly different read/write logistics.</FONT></SPAN></DIV>

<DIV><SPAN class=828593822-12052008><FONT color=#0000ff size=4>If you have and
choose to keep dirty cache, please put a UPS on the system and a battery backup
in the controller. While the setting is great for performance, it is not pretty
on failure.</FONT></SPAN></DIV>

<DIV><SPAN class=EC_515140421-12052008><FONT color=#0000ff size=4>Is there
any chance that host 1 is set to "write-through" and host 2 is set to dirty
(trust me) writes on the hardware disk controller or on the database
driver? Note how host 1 waits until all reading is done prior to the first
write - host 2 has simultaneous read/writing.</FONT></SPAN></DIV>

partitions laid out on the two systems? It is likely that
something OS related is accessing sda and sdb or host 1 while being
spread across more disks in host 2. From the output of host 2 you
provided, the first stat shows sdc is taking some of the load.
Regardless of the RAM being the same in both systems, is there much
swapping? Swapping on higher performance drives will be
quicker.</SPAN></FONT><FONT face=Tahoma size=2><SPAN

style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">I am a DBA. I have
identical database servers running on two Linux redhat 4, host 1 and
host 2. When I was running the same bulk load to database (load a
data file to database), host 2 was much faster than host 1.
<BR> <BR>On both host1 and host2, database are using file system
mount on /dev/sda and /dev/sdb.<BR> <BR>I checked with my SA,
host1 and host2 have same CPU, RAM, file system configuration. The
only different is that host 2 has extra HD capacity with higher
15k RPM. But the extra 2 HDs(sdc and sdd) are dedicated to other
applications, not used by database at all. <BR> <BR>My
questions are:<BR>-----------------<BR>1. On host2 (faster), the extra
faster HDs(/dev/sdc and sdd) are not used by database. Does it
still affect IO performance of /dev/sda and /dev/sdb ?<BR> <BR>2.
During database bulk load testing, host 1(slower) shows longer service
IO time (svctm) and longer IO waiting time(await).
<BR> What other possible reason can cause this problem?
Any idea?<BR> <BR>I did post the same issue to database
discussion group and they suggested me to check OS
performance(svctm).<BR> <BR> <BR>Below is the result from
iostat on host1(slower) and host2(faster) during bulk
load:<BR> <BR>Host 1: iostat -x
