similar to: apache slow on lan transfers?

I have a trio of servers that like to reboot during high disk / network IO operations. They don't appear to panic, as I have kernel.panic = 0 in sysctl.conf. The syslog just shows normal messages, like samba complaining about browse master and then just syslogd starting up. The machines seem to crash when I'm not near the console, usually when I'm trying to pull data off them to

I have two servers with identical hardware ... TYAN i3210w system boards with dual intel gigabit interfaces, and a PCI intel gigabit nic. I'm running Centos 5.4, x86_64, 2.6.18-164.6.1.el5 Every other time I reboot, the nics initialize in a different order. anaconda had setup /etc/modprobe.conf with alias lines for the cards: alias eth0 e1000 alias eth1 e1000e alias eth2 e1000e However,

Hi, I have installed samba on a dell poweredge server. It uses integrated NetXtreme II BCM5708 Gigabit Ethernet card. My issue is that i am getting extremely slow speeds (about 1.2MB/s) on the gigabit network from linux as well as windows clients using when reading from the samba share. On the same setup (same server, client, network) using scp,rsync,nfs gives me anything between 35-50 MB/s. So

Hello friends, I have a Gigabit network with few Windows and Centos 7 machines and I noticed that when copying files via Samba from: Windows to Windows I can copy files with speed of +- 120 MBps (I think this is the max speed gigabit network can provide) But when copying files from: Centos to Centos I get only speeds of about 40 MBps Windows to Centos 40 MBps Centos to Windows 40 MBps I

Hi all, I am trying to get to the bottom of a strange rsync performance problem. On a specific guest OS, and only on this guest OS, rsync is giving modem-like transfer speeds. This happens on delta transfers, and whole file transfers. [root at arnie ~]# rsync -avz --progress --sparse arnie.example.com:/home/backup/example/cuttysark.example.com/var-lib-libvirt-images-snapshot/

Thank you very much, I will try these. There are only Centos 7 and Windows 10 machines on the network.

My problem is there I download and archive my work to the freebsd server via samba. When I'm transfering files from the windows -> freebsd I will get anywhere between 20-100kB/s and from freebsd -> windows I will get a few mbps. I'm getting no where near a full 100mbps and both ethernet cards are set for 100mbps full duplex working great. I've tried increasing buffer sizes on

It was found that the software NIC team created in Centos was having issues due to a failing network cable. The team was going berserk with up/down changes.

Is there anyway to get gigabit networking for a fully virtualized guest? I''ve tried searching for this one, but all I get are results about gigabit networking for the host / dom0, nothing for domU.

Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

I did some additional testing - I stopped Kafka on the host, and kicked off a disk check, and it ran at the expected speed overnight. I started kafka this morning, and the raid check's speed immediately dropped down to ~2000K/Sec. I then enabled the write-back cache on the drives (hdparm -W1 /dev/sd*). The raid check is now running between 100000K/Sec and 200000K/Sec, and has been for several

A detailed description of our status and dilemma is given below... This week I've been on samba.org and searched the MARC mailing list archives for discussions pertinent to our situation. My search for "slow DOS client" produced over 100 hits dating back to the last millennium, some of which were really about something else. Many of the rest were descriptions of problems VERY

We are struggling with a strange problem. When we have some VMWare clients running (mostly MS windows clients), than the IO-write performance on the host becomes very bad. The guest os's do not do anything, just having them started, sitting at the login prompt, is enough to trigger the problem. The host has plenty of 4G of RAM, and all clients fit easily into the space. The disksystem is a

Hey! I have a strange condition in one of the servers that I don't where to start looking. I login to the server via SSH (cant doit any other way) and anything that I type is slow HTTP sessions timeout waiting for screen redraw. So, the server is acting "slow". server is bare metal. no virtual services. no alarms in the disk raid note: server was restarted because of power failure.
