similar to: Samba ignoring socket options?

Folks, I''m playing with maxbw on links (as opposed to flows) in Crossbow, and I have a couple of questions. First, the limts seem only advisory. The first example has the main host talking to a zone that has 172.16.17.100 configured on znic0. When there is no maxbw, the throughtput is as expected; when maxbw is 55M the throughput only drops to 76 Mbps: # netperf -H

Here's a weird one that may have nothing to do with Samba and more to do with network frame sizes. I have recently upgraded the network infrastructure to support gigabit speeds. - OSX Tiger to OSX Tiger file transfers operate at gigabit speeds. - Samba 3.0.23C (Suse 10) to OSX Tiger file transfers operate at gigabit speeds. - BUT OSX Tiger to Samba 3.0.23C (Suse 10) file transfers

First, I apologize if this message has been received multiple times. I''m having problems subscribing to this mailing list: Hi xen-users, I am trying to decide whether I should run a game server inside a Xen domain. My primary reason for wanting to virtualize is because I want to isolate this environment from the rest of my server. I really like the idea of isolating the game server

For an office that is using VoIP phones to connect to Asterisk, is gigabit ethernet really necessary for the Asterisk box to connect to the switch? I know that I won't even approach the limits of 100 Mbps, but would gigabit help with latency / collisions when several calls are underway? The fact is, anything going outside the office will be over a data T1, so intuition tells me that 100

Assuming in a secure and trusted env, we want to get the maximum transfer speed without the overhead from ssh. Thanks. Fred -------------- next part -------------- An HTML attachment was scrubbed...

Dear best guys, I really love 5.3 in many ways but here're some unbelievable transfer rates, after I went out and bought a pair of Intel GigaBit Ethernet Cards to solve my performance problem (*laugh*): (In short, see *** below) Tests were done with two Intel GigaBit Ethernet cards (82547EI, 32bit PCI Desktop adapter MT) connected directly without a switch/hub and "device

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, the throughput measured by netperf differs from time to time. The changeset was xen-unstable.hg C/S 11760. This is observed when I executed a netperf on DomU connecting to a netserver on Dom0 in the same box. The observed throughput was between 185Mbps to 3854Mbps. I have never seen such a difference on ia64. Regards, Hiroya _______________________________________________ Xen-devel

Hi, I wonder about the performance of a Linux box used as router (I guest I''m not the first :). Althought I know it mainly depends on the hardware, I''m trying to find some references on the topic or comparations with other routing solutions (FreeBSD box used as router, Cisco, etc). For example, http://facweb.cti.depaul.edu/jyu/Publications/Yu-Linux-TSM2004.pdf (althought is

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

Hi Is there anyone who has successfully resolved the low throughput problem in Guest communication. I am using Xen3.4.1 with PV os kernel 2.6.30-rc6-tip On fedora11. While running netperf benchmark on guests throughput results are very low DomU to DomU    0.29 Mbps Why is it so? What would be the problem. Is there any issue with fc11 platform? Regards, Fasiha Ashraf Add whatever you love

Dear All, I am having a HP xw4400 with following ethernet controller as reported by lspci Broadcom Corporation NetXtreme BCM5755 Gigabit Ethernet PCI Express (rev 02) This machine was running CentOS 5.2 without any problem. After updating the machine with yum update on 8 April, after which it is showing to be CentOS 5.3, this machine stops communicating

Hi, I've set up a bridge using the 2.6.11.6 kernel. The machine is running Debian testing with three NICs in it. eth0 is a standard 100Mb Intel NIC, eth1 and eth2 are both Intel gigabit cards using the e1000 driver. I tested everything at 100Mb and it worked fine. I moved the machine into production, eth1 plugging into a dumb 100Mb D-link switch, eth2 plugging into a shiney new Cisco

Hello again :) With POLLING enabled I experience about 10%-25% performance drop when copying files over network. Tested with both SAMBA and NFS. Is it normal?

I am trying to connect two workstations (CentOS 3&4) directly using a straight through cat 5e cable with a crossover adapter on one of the ends. Both hosts have gigabit-capable ethernet card. According to lspci host 1 has: 03:0e.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01) and host 2 has: 05:00.0 Ethernet controller: Marvell Technology Group

I recently upgraded a part of my network to Gigabit ethernet, basically between my Linux machine and my main windows machine, is now gigabit. The problem is that, and the whole reason I went with it, is to get faster speeds with samba. I've only been able to get 13.4 MB/s as a maximum transfer speed. I don't expect to be able to get 125 MB/s. If I use HTTP I can get around 18 MB/s,

Under heavy load vhost busypoll may run without suppressing notification. For example tx zerocopy callback can push tx work while handle_tx() is running, then busyloop exits due to vhost_has_work() condition and enables notification but immediately reenters handle_tx() because the pushed work was tx. In this case handle_tx() tries to disable notification again, but when using event_idx it by
