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 dbench, so I...

...all bug fixes, and I wanted to get them out there before the (destabilizing) work on multiple-devices took over. So, here's v0.12. It comes with a shiny new disk format (sorry), but the gain is dramatically better random writes to existing files. In testing here, the random write phase of tiobench went from 1MB/s to 30MB/s. The fix was to change the way back references for file extents were hashed. You can download v0.12 here: http://oss.oracle.com/projects/btrfs Other changes: Insert and delete multiple items at once in the btree where possible. Back references added more tree balan...

...ting 1 million empty files in a single dir). * When inserting back refs for file data extents, hash the offset of the extent in the file when creating the key. For extents with many references, this makes a huge difference in CPU time spent creating the back ref. For the random write phase of tiobench, btrfs v0.11 writes at 2MB/s, using 100% system cpu time. The changes I just pushed out change that to writing at disk speed. The bad news is that changing the hashing is a disk format change. I had originally planned on including the file offset in the hash, but missed it when finishing off...

Until the Escalade 9500S series matures, I've been recommending the following: 3Ware Escalade 7506/8506 for RAID-10. 3Ware Escalade 7506/8506 for RAID-5 when it is largely a read-only setup. LSI Logic MegaRAID SATA 300-8X (XScale) for RAID-5. Unless you...

Is anyone using Ext3 on a 2.4.x kernel with software raid5? Does it work correctly? Last I checked noone had tried it yet, but that was before I went away on vacation. -- Daniel R.

So I have been playing with a RAID 10 f2 ( 2 disks far layout) setup...thanks for all of the advice..Now I am playing with the format and want to make sure I have it setup the best that I can, my raid was built using the raid 10 option with 2 disks with the layout=far, chunk size 512....now I read all of the docs I could find about format and stride and stripe size and this is what i came up

I'm just wondering what folks are using to benchmark/tune large arrays these days. I've always used bonnie with file sizes 2-3 times physical RAM. Maybe there's a better way? Cheers,

Hello all, I'm creating a site where people can share their benchmarks. If you are interested, the site is at (I just started on it so it has the stock graphics and color scheme still): www.dcsnow.com/mambo I would like some thoughts on what would be a good way to standardize the testing so the results are more comparable. Is Bonnie+ a good program for hard drive speed testing? Is there

Hi everyone, This is the dm-ioband version 1.7.0 release. Dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver, which gives specified bandwidth to each job running on the same physical device. - Can be applied to the kernel 2.6.27-rc5-mm1. - Changes from 1.6.0 (posted on Sep 24, 2008): - Fix a problem that processes issuing I/Os are permanently blocked when I/O

Hello everybody, I tried to measure the performance of the available drivers for windows as a HVM guest. I used the gplpv drivers 0.9.11-pre17, the PV drivers from Novell, and the drivers from Citrix XenSource with the XenServer 5. The Novell and gplpv drivers were more or less at the same speed, for both, network and disk performance. The disk performance was about 10MB/s reading and

...data. Afterwards I checked the data with md5sum and did a fsck, everything seems to be fine so far. Was it just luck that I didn't see any data corruption? Can I use ext3 for fs >4TB<8TB on amd64 these days? I also tried xfs, but unlike ext3 it repeatable froze the system when I ran the tiobench benchmark. Ralf

I recently added a Seagate 400Gb SATA drive to my system, and it has been behaving strangely since I put it in. for one thing, the BIOS S.M.A.R.T. came up with a warning the last time I booted with it enabled, saying that I should backup my data and replace the disk (!). I still have not made any irreversible data transfers to this drive, and I have some time yet to take it back, but I'd

Everything is running with Debian Squeeze and its 2.6.32 kernel (amd64 flavour), on a 4 cores and 4 GB RAM server. I ran a tiobench tonight on an idle instance (I have two identicals systems - hw, sw, data - with exactly the same pb). I've attached results as plain text to protect them from line wrapping. They look fine to me. When I try to backup the problematic filesystem with tar, rsync or whatever tool traversing the...

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.
