I'm using glusterFs 3.03
My server is running in Heavy load, so result of your command (iozone)
may by not exactly
But I think there are problem with IO of my system, like that:
My server store many big file, for example 10000 file, each file 100MB,
so all is 10TB.
I user 12HDD SATAII , 2TB, RAID6, so enough to store files.
And problem:
- when 200 user download concurrent (normal work), Webserver must open
atleast 200 file (100mbyte/file).
Then there are 200 process open 200 file concurrently. (With Gigabit
nic, each user can reach 1Gbit /200 = 125MByte/200 ~600Kbyte/s, it's a
normal rate!)
Total IO to RAID will be ~ 1GBit <=> 125MByte/s.
With single file access, my RAID work well with this rate. But, with 200
concurrent read to RAID, I see, it can not reach 125MB/s (1 Gbit)
--> Result: With Not GluterFS, my server can not service 1Gbit/s access,
then with GlusterFS, the rate is slower?
So, What solution to resolve my hardware problem? and this solution is
still good for GlusterFS?
I see this:

I see 13GBit/s can be reached, but 64 client load with single file, so
it's simple to reach that rate?
Thank very much for your helps!

Can you tell me what version ot Gluster you are using? Also if you
could run "iozone -a -b lesonus_in_gluster.csv" in the Gluster mount
point and then again "iozone -a -b lesonus-no-gluster.csv" on the
storage server and send the results back I would appreciate it.
We should be able to get things faster for you.

Subject: Re: [Gluster-users] How about quality of GluterFS?
I need a FileHosting system can service 10, 20, ... 50Gbit ... to
service users of an ISP
With 100TB, 200TB, ... 1000 TB or more
I test with GlusterFS, with basic config, one client, one server with
Centos5.4.
I have a very basic problem: ls command is very very slow when my
system running! But I not use GlusterFS, It run normal
and change to other config of vol file, but basic problem still
So I wonder how about the Quality of GlusterFS when it has basic problem
like that!
In the future, If it can service complex and heavy load?
I need choice a suitable solution in next some days!
If GLFS can do this?
Thank you!
