<DIV><FONT size=3 face=Verdana>Hi, </FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>I am testing gluster 3.2 for LOSF (lots of small files)
scenario recently, with iozne and postmark benchmark tools. And the results show
that LOSF performance is really bad, random read/write rate is just only about 2
~ 4MB/s. I tried RAID0, RAID1, RAID10, and it's the same result. And create ops
with postmark is 100 ~ 400 per second.</FONT> </DIV>
<DIV> </DIV>
<DIV><FONT size=3>I deployed 4 bricks servers: Dell R510, 4 1TB SATA
disks, 1 GiE NIC, 8GB Mem, </FONT><FONT size=3>and test machine is also R510
with 2 SAS disks and 16GB memory. </FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>Any good ideas on gluster3.2 tunning for LOSF?</FONT></DIV>
<DIV><FONT size=3>Why dbd translator is removed from gluster 3.2?</FONT></DIV>
<DIV><FONT size=3>thanks in advance.</FONT></DIV>
