similar to: Xen performance and Dbench

hi everybody would a tool such as dbench be a valid bechmark for gluster? and, most importantly, is there any formula to estimate raw fs to gluster performance ratio for different setups? for instance: having a replicated volume, two bricks, fuse mountpoint to volume via non-congested 1Gbps or even a volume on single brick with fuse client mountpoing locally what percentage/fraction of raw

Is there any easy way in a shell script to find out the domid of "the domain I just created" with xm create? =================================== Thanks... for the memory I really could use more / My throughput's on the floor The balloon is flat / My swap disk's fat / I've OOM's in store Overcommitted so much (with apologies to the late great Bob Hope)

trying to check gluster performance with dbench I'm using a replica 3 with a bonded dual gigabit (balance-alb) on all servers and shard (64M) enabled. I'm unable to over 3MB (three) MB/s from *inside* VM, thus I think there isn't any small file issue, as from inside VM there isn't any metadata operation for gluster. Any advice ?

Hi, I got problem while using smbtorture with the NBENCH test. The error happens on the "Mkdir" operation. I'm using the file "client.txt" from dbench-3.04. There are "Mkdir" operations, but in the file "torture.c", this operation is not handled. Few other operations are not handled. I did compare operations from run_netbench and those that are present

I'm setting up a new file server and I just can't seem to get the expected performance from ext3. Unfortunately I'm stuck with ext3 due to my use of Lustre. So I'm hoping you dear readers will send me some tips for increasing ext3 performance. The system is using an Areca hardware raid controller with 5 7200RPM SATA disks. The RAID controller has 128MB of cache and the disks

Is there any piece of software that I can use to run between a client and a linux or windows server with a smb/cifs share that will test network speed, latency, sustained read/writes, multiple file create, read, write, close, etc.. etc.. over X period time? I'm testing a Centos server with samba and Windows 2k3/8 servers on the other end of a T1 connection and while I know the T1 bandwidth

Hi All, I want to test REMUS over XEN, I would like to know the basic steps to be followed . I have installed xen4.1 on debian and i didn''t find any command related to remus, is there any steps which i have to carry out? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hey guys, Has anyone had much success with XCP and Open Stack together? I''m in the process of putting together a open stack test cluster and I thought I might be able to use XCP dom0''s for it.. but to be honest it doesn''t look so good. I tried following these instructions on a separate XCP test machine: http://wiki.openstack.org/XenServerDevelopment At a first test

I''m needing to put a network card on a test server XCP 1.0. I''m seeing the citrix hcl (http://hcl.xensource.com) and I''m a doubt. I base that on which version to look for a compatible card? If the kernel is the same as in 5.6.0 FP1, but if the version of XCP uses the hypervisor 3.4.2 neither appears on the list. ps: I had a RTL-8169 but stopped working with update 0.5

I've had the chance to use a testsystem here and couldn't resist running a few benchmark programs on them: bonnie++, tiobench, dbench and a few generic ones (cp/rm/tar/etc...) on ext{234}, btrfs, jfs, ufs, xfs, zfs. All with standard mkfs/mount options and +noatime for all of them. Here are the results, no graphs - sorry: http://nerdbynature.de/benchmarks/v40z/2009-12-22/ Reiserfs

To test gluster's behavior under heavy load, I'm currently doing this on two machines sharing a common /mnt/gfs gluster mount: ssh bal-6.example.com apt-get install dbench && dbench 6 -t 60 -D /mnt/gfs ssh bal-7.example.com apt-get install dbench && dbench 6 -t 60 -D /mnt/gfs One of the processes usually dies pretty quickly like this: [608] open

Hello, Queries: 1 - what is the best RAID (0,1,5,10,50) for server running very, very VM instances ??? 2 - and config of stripes/element sizes (32, 64, 128, 256, etc, KB) ?? 3 - in the configuration of VM, exit one difference in performance between image file (disk:/) or LVM partition (phy:/) ??? any URL or docs for read about this theme ? mmm.. it is all for moment. thanks -- -- Victor

Hello, I have a Gentoo Linux guest, which was working very well with the past xm tool stack. Since the migration to xen-4.1.1 and to the new xl tool stack, I have a problem for the IP assignation. Actually, when dhcpcd starts at boot time the IP address is not correctly assigned. This also happens if I perform "dhcpcd eth0" once I''ve accessed to the guest shell. I

Hello Everyone, I am new with XCP. I''ve setup several hosts with* XCP 1.0* and manage it through XenCenter and command console. Each host has two NICs, one (xenbr0) connected to a physical switch for Internet (said sw1), the other (xenbr3) connected to a physical switch for internal network (said sw2). I am trying to setup VMs and VLANs on xenbr3. I created a virtual bridge by

I would like to install XCP. So I started at http://www.xen.org/products/index.html and found the section labeled ''Xen Cloud Platform Project'' This section was a nice overview but no links to docs or downloads. The next section was labeled ''USERS'' which had a download link to ''Xen Cloud Platform 1.5 Beta Download''

Due to recent changes in timer handling (specifically building hpet emulation on top of Xen system time and ensuring it is monotonic), I wonder if it now makes sense to: 1) change hvm default for hpet to 1 (was 0) 2) change hvm timer_mode default from 0 to 2 I encouraged adding the hvm hpet parameter and defaulting it to 0 because the virtual hpet was not reliable and many guests/versions

Hai, I am using dell insprion 580 machine for xen installation and dom0 configuation. I compiled xen source code and configured the kernal.
