Hi, we have network performance issues with Samba (Version 4.2.7-SerNet-RedHat-19.el6) on one of our servers. The maximum throughput from client to server is 110 MB/s (read/write) under Windows 7 x64 (single 10GE NIC). When using NFS on a different Linux workstation we're getting much higher rates, around 500-700 MB/s. I still can't find the problem.

...mance issues. Today, I've been able to nail it down to a simple test case. What strikes me is that Windows XP takes about 25 seconds for one job, while it only costs 3 seconds on Windows 7. I have two tests: 1000 files of 10k each (total ~10Mb): * Linux on localhost or a remote host (1GE or 10GE): 5.5 seconds * Windows XP - Machine #1: 24.5 seconds * Windows XP - Machine #2: 60 sec * Windows 7 - Identical hardware as XP machine #1: 3 seconds One 500MB file: * Expected result: 4-5 seconds on 1Gbit (100-125Mbyte/s) * Linux on localhost: 0.5 sec * Other Linux machine with 10GE connect: 0.9 s...

Hi Is there clean way to ensure that a glusterfs mount point specified in /etc/fstab is mounted automatically on boot under debian lenny when referencing a remote node for the volfile? In my test case everytime I reboot, the system tries to mount the filesystem before the backend 10ge interface comes up so it gets a "No route to host" and immediately aborts. I know I can dump a mount -a into /etc/rc.local but I'm hoping there's a more elegant way to handle this scenario. The fstab entry contains options noatime,_netdev already. Thanks. Mohan

...e number of AnyConnect Premium Peers has been increased from 2 to 50 after license activation. [2] Configuring NIC teaming/bonding on CentOS 8.2 (2004) Linux Server Today I had to configure NIC teaming/bonding on CentOS 8.2 (2004) Linux Server. The server hardware is Dell PowerEdge R640 with 2x 10GE NIC ports and 6x 1GE NIC ports. NIC teaming/bonding was configured using 2x 10GE NIC ports. All I had to do is to follow the following reference guide.

Hi there, This is a hypothetical problem, not one that describes specific hardware at the moment. As we all know, gluster currently usually works best when each brick is the same size, and each host has the same number of bricks. Let's call this a "homogeneous" configuration. Suppose you buy the hardware to build such a pool. Two years go by, and you want to grow the pool. Changes

Hi, We run four-node Lustre 2.3, and I needed to both change hardware under MGS/MDS and reassign an OSS ip. Just the same, I added a brand new 10GE network to the system, which was the reason for MDS hardware change. I ran tunefs.lustre --writeconf as per chapter 14.4 in Lustre Manual, and everything mounts fine. Log regeneration apparently works, since it seems to do something, but exceedingly slowly. Disks show all but no activity,...

Hi everybody, I have a question about network interface used for tiering in glusterfs, if I have a 1G nic on glusterfs servers and clients, can I get more performance by setting up glusterfs tiering?or the network interface should be 10G? -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I maintain a driver for a 10GbE nic which supports multiple hardware tx/rx rings. We can steer rx packets into rings using the "standard" NDIS6 Toeplitz hashing on TCP port numbers, IP addresses, etc. We can also steer packets based on MAC address. Would this NIC be considered to be capable of supporting crossbow? Also, can crossbow do things like steer outgoing packets to the

...I/O > > It doesn't matter what I expect. It *does* matter if you know what the hardware?s capable of. TLS is a much harder problem than XOR checksumming for traditional RAID, yet it imposes [approximately zero][1] performance penalty on modern server hardware, so if your CPU can fill a 10GE pipe with TLS, then it should have no problem dealing with the simpler calculations needed by the ~2 Gbit/sec flat-out max data rate of a typical RAID-grade 4 TB spinning HDD. Even with 8 in parallel in the best case where they?re all reading linearly, you?re still within a small multiple of the E...

...rdware instance and the other way around. I tried Debian Xen and vanilla Xen and also using Debian Xen kernel and Debian bpo kernel as a dom0 kernel. I did try setting the dom0 memory to various sizes and iommu=1 as well. Finally I retried most test scenarios with irqbalance enabled, as those Intel 10GE cards expose between 8 and 16 queses (IRQs) for TX/RX, depending on the kernel version. The result is always the same: I am limited to 250MByte/s max. unless both boxes run on bare hardware. Even Debian Xen kernel on bare hardware on both boxes does about 550MByte/s. When testing dom0 performance,...

I'm currently using it, and the performance sucks. Perhaps it's not the software itself or the CPU but the on-board controllers or other

...ase the compute throughput. The future does not seem brighter in that area. In the meantime, network bandwidth has still increased at a regular pace. As a result, a cpu frequency that was once sufficient to fill the network pipe is now only at a fraction of what the network can really deliver. 10GE ethernet cards are common nowadays on datacenter servers and no openssh ciphers and MACs can deliver the available bandwidth for single transfers. Introducing parallelism is thus necessary to leverage what the network hardware can offer. The change proposed by Cyril in sftp is a very pragmatic...

Hi all after being a silent reader for some time and not very successful in getting good performance out of our test set-up, I'm finally getting to the list with questions. Right now, we are operating a web server serving out 4MB files for a distributed computing project. Data is requested from all over the world at a rate of about 650k to 800k downloads a day. Each data file is usually

Hello, I'd like to share with you an evolution I made on sftp. 1. The need I'm working at CEA (Commissariat ? l'?nergie atomique et aux ?nergies alternatives) in France. We have a compute cluster complex, and our customers regularly need to transfer big files from and to the cluster. Each of our front nodes has an outgoing bandwidth limit (let's say 1Gb/s each, generally more
