similar to: smbd write performance depending on windows operating system?

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

connection will remain a TCP connection unless it is broken and restarted. Usually if I stop the client and wait for about 30 seconds to reconnect, there is a much greater chance that the MTU probes work fine, and in about 30 seconds MTU is fixed to 1416. Every time when the MTU probing fails, I see latency between 700 - 1000 ms with 32 byte pings over a LAN. Every time when the MTU probing does

A number of years back it became necessary to limit the size of messages that could be posted to the samba mailing list. The current limit is 64 KBytes. While it continues be be desirable to block large spam messages, I believe it is time to ask current subscribers for their preferences. This list is here to serve the wishes and needs of our subscribers. We wonder if the time is right to review

Hi, I am testing tinc for a very large scale deployment. I am using tinc-1.1 for testing. test results below are for tinc in switch mode. all other settings are default. test is performed in LAN env. 2 different hosts. I am getting only 24.6 Mbits/sec when tinc is used. without tinc on the same hosts/link I get 95 to 100 Mbits/sec using iperf. Over Tinc: iperf -c 192.168.9.9 -b 100m -l 32k -w

Hi, below are some test results from implementing a prio qdisc ''that is also below''. The qdisc is attacted to a vlan interface for my external network. Both tests were run at the same time. The links are policed at 6.0M ''by our provider''. 192.168.70.1 --> 192.168.30.1 My question is: If using a prio qdisc should''nt the iperf run with a tos of b8 have

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

I did some testing using samba-3.0.0 as a server and two identical clients one Running W2K and other running Win XP pro. If I write a big file using the W2K client, I'm getting about 25 Mbytes/sec but if I run the same testing using the Win XP Pro, this client only is able to get 12.5 Mbytes/sec. There is a problem between XP and samba?

I have two boxes for the purpose of testing traffic control and my knowledge thereof (which is at the inkling stage). The boxes are connected by 100Mbit ethernet cards via a switch. For egress traffic via eth0 I achieve a throughput that is close to the specified CEILing, particularly for values above 1mbit. Ingress traffic does not seem so well behaved. Above about 1mbit rates achieved are

Howdy: This is (at least slightly) off-topic, but I've seen more knowledgeable folks than I mention autonegotiation in this venue and, since I didn't get any response on the vortex-bugs mailing list, I thought I'd ask here (also, the interface in question supports samba so...). And there should be some good news for some folks too. If this is old news, sorry (I've been too busy

Hi, I'm having some weird problem with the setup of the QoS on a bridged network. As the docs states, outbound/inbound average speed should be expressed in KBps (KBytes per second) but in order to get a maximum speed of 10Mbps (megabits per second) surprising enough I have to use 2560 on the guest (not 1280 as expected). Using 1280 units I get a speed og 5Mbps. I'm aware of peak and

Hi all, I'm confused of small files (no bigger than 50k ) transfers speed through samba,which is very slow on my machine. Bellow is a real case, -- SuSE professional 9.2, kernel 2.6.11,Samba 3.0.14a,reiserfs -- Dual AMD Opteron,4G mem,Giga byte LAN -- 2 raid 5 make up of 16 SATA hard disks -- set readhead to 1024 I tested raids speed using bonnie++ and get 450 Mbytes/s at 16GB files

Hi, In a setup where OpenVSwitch is used with GRE tunels on top of an interface provided by tinc, I'm experiencing significant performance degradation problems (from 100Mb/s down to 1Mb/s in the worst case) and I'm not sure how to fix this. The manifestation of the problem is, from the user point of view, iperf reports ~100Mb/s and rsync reports ~1Mb/s: $ iperf -c 91.224.149.132

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

Hello, I recently set up a samba cluster with 4 nodes using ctdb. The systems are virtual Citrix xen machines running SuSE SLES11Sp2 with samba 3.6.3. The shared filesystem needed for ctdb is on a ocfs2 share stored on a ISCSI target. The cluster is running fine and ip takeover etc is working fine as well. To find out how the cluster would performe in real life with many clients accessing

Hi, I am seeing a performance degradation while using libvirt to start my vm (kvm). vm is fedora 12 and host is also fedora 12, both with 2.6.32.10-90.fc12.i686.

Dear R gurus and users, I'm having problems with the use of write.table. I have a 28-variables data frame create at each cycle of a loop; it can contain between 2000 and 3000 rows for each cycle. After each cycle the data frame is written out to a file with the "append=TRUE" option and then removed from memory. These are the couple of lines involved: > data2 <-

I hace just installed samba. It works fine using application on my debian, but from Win98 can not see my samba. I can not achieve to see my samba as part of the NT domain. If I try to find \\mysamba\share (where mysamba is my netbios name) Win98 says "Error 53" Unknown hosts or route to host (in spanish) using my IP instead of "mysamba" produces the same result on Win98, but

Hi all. I have a problem with the cifs module in my gigabit network. I get the following performance: 95 mbytes/s with FTP 65 mbytes/s with samba, windows 7 client 8 mbytes/ with the cifs module on opensuse 11.4 I have tried all the solutions found on google, such as directio, modifying rsize and wsize, with no improvements. Any advice? Is this the right place to discuss issues with cifs? P
