Hi Gang, I recently rented a server at a datacenter with Centos 5.7 X64, Q9550 Processor, 8GB Ram, and dual 250GB SATA HDs (with 16mb cache). They had loaded it with KVM, and installed a 30-day trial of Virtualizor as the front-end for KVM. I was so impressed with how fasts the guests ran that I want to build a few of these machines for myself. I just installed one: same Q9550 processor, 4GB

Tony?s performance sounds significantly sub par from my experience. I did some testing with gluster 3.12 and Ovirt 3.9, on my running production cluster when I enabled the glfsapi, even my pre numbers are significantly better than what Tony is reporting: ??????????????????? Before using gfapi: ]# dd if=/dev/urandom of=test.file bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824

Hi. I have 2 PC's connected with 1GBit NIC's. When I transfer a file from my File-Server(Redhat9.0, 256 SD-RAM, 300MHz PII, RTL8169 NIC, 2x Western Digital WD200JB RAID 0) to my Windows-PC(AMD Athlon XP 1800+, 1024 MB DDR-RAM, WINXP PRO, RTL8169 NIC, 2x Western Digital WD080JB RAID 0) with Samba, i get Speeds around 8-9MB/sec. I think this is too low for an GBit Network, so i tested the

Hi, I was wanting to run the equivalent of "hdparm -Tt /dev/hda" except on a SATA hard disk. What is the equivalent command for an SATA drive? I was wanting to see what kind of speed I am getting on the SATA drive. thanks, Jerry

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

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 All - I use qemu on my centOS 7.7 box that has software raid of 2- SSD disks. I installed an nVME drive in the computer also. I tried to insall CentOS8 on it (the physical /dev/nvme0n1 with the -hda /dev/nvme0n1 as the disk.
