Hi, We are running on 5.5 on a HP ProLiant DL360 G6. Kernel version is 2.6.18-194.17.1.el5 (we had also tested with the latest available kernel kernel-2.6.18-238.1.1.el5.x86_64) We running some performance tests using the "iperf" utility. We are seeing very bad and inconsistent performance on the UDP testing. The maximum we could get, was 440 Mbits/sec, and it varies from 250 to 440

Currently I'm running CentOS 4.4 on a Dell Poweredge 850 with an Intel Pro/1000 Quad-port adapter. I seem to be able to only achieve 80% utilization on the adapter, while on the same box running Fedora Core 5 I was able to reach 99% utilization. I am using iSCSI Enterprise Target as my application and I am using the nullio feature, it just discards any write and sends back random data for

Hi, On one of our asterisk systems that is quite busy, we are seeing the following from 'netstat -s': Udp: 17725210 packets received 36547 packets to unknown port received. 44017 packet receive errors 17101174 packets sent RcvbufErrors: 44017 <--- this When this number increases, we see SIP errors, and in particular Qualify packets are lost, and

Hi I was wondering if you ever got better performance out of your Gigabit/IDE/Fc2? I am facing a similar situation. I am running FC2 with Samba 3.x My problem lies in not that I am limited to 10 MBytes per second sustained. I think it's related to this pdflush and how it's buffers are setup. (I have been doing some research and before 2.6 kernels bdflush was the method that was used and

i am assigned a network to replace its "Windows server with ISA caching proxy" with another "debian linux with squid proxy" with both "linux" and "ISA" are completely differnet boxes. i am using linux 2.6 kernel since the linux server has SATA hard disks . the network has downlink with a penta@net DVB card for down-link ; then it''s connected

Hi all, I order to reach maximum performance on my centos kvm hosts I have use these params: - On /etc/grub.conf: kernel /vmlinuz-2.6.18-164.11.1.el5 ro root=LABEL=/ elevator=deadline quiet - On sysctl.conf # Special network params net.core.rmem_default = 8388608 net.core.wmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216

Hi all, I'm just wondering why smbmount allows the same mount point to mount several times the same share while a normal mount operation (with a non-smbfs) returns a busy mount point error. [luca@fluca:~]$ mount ... //server/sys on /mnt/target type smbfs (rw) [luca@fluca:~]$ smbmount //server/sys /mnt/target/ -o ip=192.168.4.1,guest [luca@fluca:~]$ mount ... //server/sys on /mnt/target type

I'm using debian Sarge, Samba 3.0.6-3, Kernel 2.6.8 I use smbmount //server/share mymountpt -oguest which connects fine, but it all dies (hangs) if I try to look in that mounted directory with konqueror in kde OR nautillus in gnome. In dmesg of the server computer I get: smb_proc_readdir_long: error=-512, breaking and the same but with error -13 smb_add_request ... Timed Out! this last

I have four NFS servers running on Dell hardware (PE2900) under CentOS 5.7, x86_64. The number of NFS clients is about 170. A few days ago, one of the four, with no apparent changes, stopped responding to NFS requests for two minutes every half an hour (approx). Let's call this "the hang". It has been doing this for four days now. There are no log messages of any kind pertaining

I posted back in January about a huge performance gap I was seeing on a gigabit network when comparing smbfs and smbclient operations. I was advised to try CIFS, which I did. I didn't make much difference and I gave up and switched to NFS. Recently, however, I noticed something odd. If I move files separately across my smbfs mount, things go MUCH faster. Here's an example. I mount my

Ok so maybe someone can explain this to me. I've been banging my head against the wall on this one for several weeks now and the powers that be are starting to get a little impatient. What we've got is an old FoxPro application, the FoxPro .dbf's being stored on a Linux fileserver using Samba (Fedora 3 currently, using Fedora 5 on the new test server). We're having speed

Hi everyone, I am seeing slower-than-expected performance in Gluster 3.2.3 between 4 hosts with 10 gigabit eth between them all. Each host has 4x 300GB SAS 15K drives in RAID10, 6-core Xeon E5645 @ 2.40GHz and 24GB RAM running Ubuntu 10.04 64-bit (I have also tested with Scientific Linux 6.1 and Debian Squeeze - same results on those as well). All of the hosts mount the volume using the FUSE

Hello everyone. What's better for Asterisk: have 2 distinct 100Mb network cards in the system, one on the "internet" and one on the "local net" OR have one 1000Mb network card with 2 separate VLAN's set up? It's a difficult decision because 2 cards are using 2 IRQ's etc but a single 1000Mb card might generate more PCI interrupts and get me into different

I have no output in the logs, but /etc/init.d/network restart fixes the issue. I am rsync/scp (10GB) data from one 100MB Full duplex host to an ASUS M3A78-EM (RTL8111B/C). It locks up around the 1.5GB Tx mark. If I ethtool -s eth0 autoneg off speed 100 duplex full it does not happen again. Ideas? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -

Greetings all- I have a CentOS 5 (Final) system that is serving up content to several other hosts via NFS. The amount of data transferred is rather small as most of the files are under 100kb and each export has maybe 100 files that are accessed regularly. I'm finding that as I add more hosts accessing the NFS server, the performance seems to be getting poorer. There are obvious delays when

would like some input on this one please. Two CentOS 5.5 XEN servers, with 1GB NIC's, connected to a 1GB switch transfer files to each other at about 30MB/s between each other. Both servers have the following setup: CentOS 5.5 x64 XEN 1GB NIC's 7200rpm SATA HDD's The hardware configuration can't change, I need to use these servers as they are. They are both used in production

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
