Hey guys.. I just installed and ran iozone.. neat tool..
However.... I am very concerned about the "write" performance of my
system...
When the file size reaches 32Mb, I see a huge drop from around 129Mb/sec
(obviously caching effects) right down to 10Mb/sec... then at 64Mb it drops
to between 2.5 and 6.7 Mb/sec depending on record/block size...
I have a Dual Intel PIII 500 system with 256Mb of main Memory... It has a
Hardware RAID 5 system on 5 18 Gb Seagate Barracuda drives spread over 3 LVD
SCSI channels on a Megaraid controller. I have the latest megaraid source
(1.05) from ami.com.
Any ideas how I can get more performance out of this machine? What is the
best configuration when creating the filesystem? I used mke2fs -b 4096 -i
8192 ...
Any help would be most appreciated!!
Regards,
Matthew Clark.
