similar to: Samba performance

Reading a flat text file 138 Mbyte large into R with a combination of scan (to get the header) and read.table. After conversion of text time stamps to POSIXct and conversion of integer codes to factors I convert everything into one data frame and release the old structures containing the data by using rm(). Strangely, the rm() does not appear to reduce the used memory. I checked using

Hi! I do a rsync between 2 machines. The throughput is only 2 MByte/Sec. Each machine is a Supermicro server with 2 x 8 Core Opteron 6128 64 GByte of ECC RAM 1 LSI MegaRAID SAS 9280-24i4e 24 x 2TByte SATA Disks as a RAID6 2 Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network-cards Both run Ubuntu 11.04 64Bit. Both use rsync version 3.0.7 protocol version 30 There are no

Hi all, I've got two gigabit ethernet interfaces bonded in CentOS 5.6. I've set "miimode=1000" and I've tried "mode=" 0, 4 and 6. I've not been able to get better than 112MB/sec, which is the same as the non-bonded interfaces. My config files are: === cat /etc/sysconfig/network-scripts/ifcfg-{eth1,eth2,bond0} # SN1 HWADDR=00:30:48:fd:26:71

Currently the resize command is under filesystem, and takes a path to the mounted filesystem. This seems wrong to me. Shouldn''t it be under device, and take a path to a device to resize? Otherwise, how can a resize operation when you have multiple devices make any sense? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to

I have a Dell server with four bonded, gigabit interfaces. Bonding mode is 802.3ad, xmit_hash_policy=layer3+4. When testing this setup with iperf, I never get more than a total of about 3Gbps throughput. Is there anything to tweak to get better throughput? Or am I running into other limits (e.g. was reading about tcp retransmit limits for mode 0). The iperf test was run with iperf -s on the

Hi all, I am trying to get some decent speed out of a vanilla Debian (Proxmox) box and am running out of ideas. Basically I can exchange data at 110MB/sec (raw, nfs, ftp) but not with Samba shares. I tried almost every samba tuning tip I could find to no avail. The only optimisation left to smb.conf at the moment is debug level = 0. As one can see the robocopy throughput is merely half of what

On RedHat Enterprise Linux 6, the test below fails (this is using the stock GCC 4.4.7) from R-devel r72707. LC_CTYPE is unset when I run it, but LANG=en_US.UTF-8 It also failed "yesterday" where as far as I recall the test code looked a bit different.

All- Per this page https://rwmj.wordpress.com/2013/04/22/using-rsync-with-libguestfs/ We are trying to get the libguestfs API guestfs_rsync_out to work. We’ve tried combinations similar to: guestfs_rsync_out(g, “/HostShared”, “rsync://root@10.0.1.90:2999/backup/ -av”, -1) surrounding it with APIs as in the recipe examples, for example replacing libguestfs_cat(), with no luck. In the

Hello Xen-Users, I am running a Debian GNU/Linux Devel-Station (P2/366 MHz, 512MByte) and use currently chroots which give some problems from time to time.

I have some questions about the choice of SSDs to use for ZIL and L2ARC. I''m trying to build an OpenSolaris iSCSI SAN out of a whitebox system, which is intended to be used as a backup SAN during storage migration, so it''s built on a tight budget. The system currently has 4GB RAM, 3GHz Core2-Quad and 8x 500GB WD REII SATA HDDs attached to an Areca 8port ARC-1220 controller

??Hi all! We use Samba 3 server for some video stuff (editing, rendering, and so on) -- that's why performance is critical. We've tried a lot smb.conf options, but Samba can't satisfy our requirements.

I'm trying to test out an Equallogic PS5500 with a server running CentOS 4.7 I can create a volume and mount it fine using the standard iscsi-initiator-utils tools. The Equallogic box has 3 Gigabit interfaces and I would like to try to set up things so I can read/write from/to the volume using multiple NICs on the server i.e. get 200+ Mbyte/s access to the volume - I've had some
