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

Okay, I've been chasing performance for a while now. I have no idea if I should be trying to get better performance or if I'm getting all I can out of my hardware. Here is the information: /sbin/hdparm -I /dev/hdd /dev/hdd: ATA device, with non-removable media Model Number: ST328040A Serial Number: 7BY034XB Firmware Revision: 3.07 Standards:

Hi, we have a storageserver (Centos 6.4) with a dualport Intel 10G X520-2 Adapter. A QSan P600Q-D316 Storage is configured with 8*SATA Drives raid 5 for test, connected trought a Cisco UCS 6100 Series Fabric Interconnect 10G Switch. I formated the storage with ext4 defaults, one volume and got r/w rates about 10MB/s some up to 40MB/s .... VERY POOR.... So we returned the storage to our dealer

Hi, community Please, help me with my trouble. I have 2 Gluster nodes, with 2 bricks on each.

Is this a protocol issue? A decade ago I saw writes to small files less than 16k were awful, because the cost of opening and other file ops dwarfed writing actual content. So very small files should be slow, but these files are 10mb each. Or is this a Windows issue? If so, what's causing the problem? Just trying to understand.

Hello all, I have 2 identical Dell r510 servers with 10gig card, running centos 6 with samba-3.5.4-68.el6_0.2.x86_64. I setup 16G ramdisk samba share on both and ran cp from local ramdisk to samba ramdisk mount. If I cp 12 1-gig files, I get combined 100MB/s transfer rate. Single file cp maxes out at about 15MB/s. Ftp transfer give me over 300MB/s. Running with 9000 MTU. Most smb.conf is

Dear List: I have a network (about 30 PCs) that was working fine using SECURITY=USER. Last weekend we switched over to take advantage of a Win2K server (recently added to the network) to be used as a PDC, Active Directory, etc. The network clients are a mix of WinXP, Win2K-SP3, and WinNT-SP5. After the switch, the WinXP clients started experiencing a severe slowdown after a short period of

Hi all, I know this subject is extensively discussed on the mail list but I did not get the solution yet.. I have a server running RedHat Linux 7.2 (2 CPU, 4 Gb RAM) and 6 client machines running RedHat linux 7.1 ( 1 cpu(2Ghz),512 Mb RAM ). I am backing up the client machine every 15 minutes since these machines generates important data. I am using rsync as a cron job on the server to backup

Hi, After our upgrade from Samba 3.x to 4.1.6 we are having major performance issues. Today, I've been able to nail it down to a simple test case. What strikes me is that Windows XP takes about 25 seconds for one job, while it only costs 3 seconds on Windows 7. I have two tests: 1000 files of 10k each (total ~10Mb): * Linux on localhost or a remote host (1GE or 10GE): 5.5 seconds *

Hi, I've a strange issue with the performance of file transfers between a Samba server and a Vista client. My configuration looks like this: fileserver: Samba 3.3 on FreeBSD 6.2 ----- gbit switch ----- workstation: Vista x64 When transfering files between the two PCs, I get abount 6.5 to 7 MB / sec. On my last Vista installation I got about 40 MB / sec. I've tried the following: -

Hi, I have a fedora21 system that's been running fine under normal network activity, but trying to perform a full backup of the 300GB filesystem is taking forever because the network speed appears to be very slow. Using rsync, the transfer speeds reach a max of like 180kB/s. Using rsync to copy files on the local filesystem is greater than 55MB/s, so I don't think it's a disk

Hello, I had some troubles with samba performance after I switched my network to gigabit ethernet: FTP gave 50MB/s (on a 5GB file) NFSv3 40MB/s (win xp client with SFU, free nfs client for windows) Samba (win XP client) only 15MB/s. After some fiddling with options, I found out that setting write cache size to 256KB resulted in a very big performance improvement, now also samba gabe 40MB/s.

In an architecture where we have Samba running on RHEL exposing shares to Windows, when we have 1 large 1GB file, the write performance to storage is very fast, even over distances of 5000 miles. However, even writes to local Samba servers, with 100 10MB files being copied onto a shared drive, Windows Explorer is MUCH slower. I don't know if it's really Samba, but more than likely Windows.

hi, all: I'v got a Gluster testing, and found some performance issuse pertain to Gluster I built a ten-node Gluster enviroment, (3 X HP 380G5, 4 IBM 3650, 2 X HP C7000. 1 X DELL PE2950, all the network switch & NICs are all gigabit). And set up three volumes: a ten-brick distribute volume (ten-brick means this volumes resides on ten nodes, others are same), a five-brick distribute

------- TL;DR ------- Performance seems slow (around 300-400Mbit peak). How to improve? ------- The Long Version ------- I tried to test tinc performance for an upcoming project that may need to use NFS over a VPN. Our current tinc network seems to be able to transmit at around 30-40 MB/s. (I used an 1GB random testfile to copy to/from /dev/shm/; using netcat and http.) In comparison, HTTP and

Hello. I'm experiencing slow performance when clients read from a share on Samba 3.0.24. My clients are mostly Windows XP, 2k and maybe Vista. I've eliminated all possible bottlenecks. The filesystem doesnt' slow me down, nor the lvm'ed disks, as you can see here: (I used pipemeter & cat - poorman's tools - to test. If you'd prefer anything else please advise on what

Is the rsync a first copy or are you overwriting a previous copy. How fast is the transfer rate with scp? -----Oorspronkelijk bericht----- Van: Alex Regan [mailto:mysqlstudent@gmail.com] Verzonden: maandag 29 juni 2015 4:46 Aan: libvirt-users@redhat.com Onderwerp: [libvirt-users] Slow network performance issues Hi, I have a fedora21 system that's been running fine under normal network

I can't seem to get the read and write performance better than approximately 40MB/s on an ext2 file system. IMO, this is horrible performance for a 6-drive, hardware RAID 5 array. Please have a look at what I'm doing and let me know if anybody has any suggestions on how to improve the performance... System specs: ----------------- 2 x 2.8GHz Xeons 6GB RAM 1 3ware 9500S-12 2 x 6-drive,

Thanks for the tip but recompiling the latest version was the second thing I did after trying and failing to tweak the smb.conf on my original hardware conf. I found that compiling it for my specific architecture (i686) increased my performance by 100% (from a punny 0.8 MB/s to a better but still punny 1.6 MB/s). -----Original Message----- From: Diego Julian Remolina
