Hi all, I''ve got a solaris 10 running 9/10 on a T3. It''s an oracle box with 128GB memory RIght now oracle . I''ve been trying to load test the box with bonnie++. I can seem to get 80 to 90 K writes, but can''t seem to get more than a couple K for writes. Any suggestions? Or should I take this to a bonnie++ mailing list? Any help is appreciated. I''m kinda new to load testing. Thanks. -------------- next part -------------- An HTML attachm...

Greetings I've searched to no avail so far... there is bound to be something more intelligible out there...??? I am playing with bonnie++ for the first time... May I please get some advise and list experience on using this or other disk subsystem benchmark programs properly with or without a GUI ? Test system in this case is a Compaq DL360 with 2 to 4 Gig DRAM and qty (2) 36Gig 10k drives in hardware raid1 (raid1 default 128k) an...

We're trying to setup a dual-primary DRBD environment, with a shared disk with either OCFS2 or GFS. The environment is a Centos 5.3 with DRBD82 (but also tried with DRBD83 from testing) . Setting up a single primary disk and running bonnie++ on it works. Setting up a dual-primary disk, only mounting it on one node (ext3) and running bonnie++ works When setting up ocfs2 on the /dev/drbd0 disk and mounting it on both nodes, basic functionality seems in place but usually less than 5-10 minutes after I start bonnie++ as a test on one o...

...have used mdadm to configure the array. RAID bus controller: Intel Corporation 82801 SATA RAID Controller For a simple striped array I ran: # mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/sdb1 /dev/sdc1 # mke2fs -j /dev/md0 # mount -t ext3 /dev/md0 /mnt Attached are the results of 2 bonnie++ tests I made to test the performance: # bonnie++ -s 256m -d /mnt -u 0 -r 0 and # bonnie++ -s 1g -d /mnt -u 0 -r 0 I also tried 3 of the drives in a RAID 5 setup with gave similar results. Is it me or are the results poor? Is this the best I can expect from the hardware or is something wrong...

...use the two devices to assemble a software raid device (/dev/md0) - On the /dev/md0 I create a lvm volume group and lvm volumes on it. Everything seems to work fine if the lvm volumes on the DomU are lightly used. Under heavy load the DomU freeze up immediately. The i/o tests are performed with bonnie++ This is the DomU configuration file: # -*- mode: python; -*- kernel = "/boot/vmlinuz-2.6.18-6-xen-amd64" ramdisk = "/boot/initrd.img-2.6.18-6-xen-amd64" memory = 256 name = "apollo" vif = [''bridge=xenbr0''] disk = [''fil...

...r promise for data integrity, which is my primary concern. However, naturally, I decided to do some benchmarks in the process, and I don''t understand why the results are what they are. I though I had a reasonable understanding of ZFS, but now I''m not so sure. I''ve used bonnie++ and a variety of Linux RAID configs below to approximate equivalent ZFS configurations and compare. I do realise they''re not exactly the same thing, but it seems to me they''re reasonable comparisons and should return at least somewhat similar performance. I also realise bonnie...

I wanted to see how btrfs compares to other filesystems so I have been running bonnie++ on it. While the results are good(much faster then ext2) every once in awhile I get a kernel oops. I am testing on xubuntu 8.10 with the 2.6.27-7-686 kernel using the latest git sources. Most of the time the oops happens within 20min of running bonnie++ but sometimes it takes a few hours. This ha...

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 is locking up during d...

Hi all I tried to run bonnie++ disk stresser in dom-U, who''s disk is backed with non-local (on nfs) loop-back file. The machine rebooted pretty quickly. So, how do I tell what''s barfing? Is it Xen? Is it dom-0 (nfs or loop-back)? I looked in dom-0''s /var/log/messages and didn''t see any o...

...ill 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 each have 8MB. The cache is write-back. The system is Linux 2.6.12 on amd64 with 1GB system memory. Using bonnie++ with a 10GB fileset, in MB/s: ext3 jfs xfs Read 112 188 141 Write 97 157 167 Rewrite 51 71 60 These number were obtained using the mkfs defaults for all filesystems and the deadline scheduler. As you can see JFS is kicking butt on this test. Nex...

Hi folks, For people who might be interested, here is how btrfs performs with two partitions on a single SSD drive in a RAID-1 mirror. This is on a Dell E4200 with Core 2 Duo U9300 (1.2GHz), 2GB RAM and a Samsung SSD (128GB Thin uSATA SSD). Version 1.03c ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block--

Hi Folks, I was wondering if anyone has an pointers/suggestions on how I might increase disk performance of a HVM zvol-backed DomU? - this is my first DomU, so hopefully its something obvious Running bonnie++ shows the DomU''s performance to be 3 orders of magnitude worse than Dom0''s, which itself is half as good as when not running xVM at all (see bottom for bonnie++ results) I''m using a 2*raidz2 SAN for the DomU backing. I''m also using a separate disk (a compact...

we just purchase new I/O card and like to check I/O performance. for sequence I/O performance test we can use "hdparm -t /dev/xxx" bur for random I/O performance test which Linux command I can use? ** our environment does NOT allow install third party software.. Thanks
