Dear Icecast, We are operating a web radio on a 10 Gbps dedicated server line. The line bandwidth is tested and available. The web radio is hosted on a Proxmox virtual environment. We own the physical server itself and made sure to have allocated the sufficient amount of resources on the virtual machine. We found that no matter what we do overall uploa...

Dear Marius, In addition to that attached please find a screenshot from Proxmox on statistics. Do you know any ice cast servers that puts out more than 1 gbps for a longer period? Just curious whether anyone was able to go beyond 1 gbps for an extensive time. Thank you!

...xsl For the slave: http://45.67.158.94:8000/status.xsl We are peaking at around 11.00 am and 13.00 pm in the afternoon. We have tested extensively the bandwith with speedtest. We tried with iperf but that did not finish for a long time so we stopped it. Currently we are load balancing on two 10 gbps dedicated lines. So for now we are ok, but for the future we do not know for how long it will last. Currently we are limiting the number of listeners to 5200 on each server so as not to cripple the system. When we are approaching the bandwidth limit we are getting loads of timeouts until finally no...

I don't know if any such limitation exists, but maxing out just shy of 1Gbps sounds a bit more like an interface's line speed limited/set to 1Gbps somewhere in your production chain? You wrote that you have tested the bw - what did you use? Iperf? Speedtest?Maybe consider scaling with additional Icecast servers and use a load balancer in front? And then just scale accor...

Hi guys, I'm yet to use 10 Gbps with CentOS, hence my question. I'm looking for a cheap (doh) adapter that won't cause me problems with CentOS. Any recommendations? Cheers Lucian -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro

Hi! I am building a KVM cluster that needs VM live migration. My shared storage as well as the KVM hosts will be running CentOS. Because 10 Gbps Ethernet switches are very expensive at the moment I will connect the KVM hosts to the storage by cross-over cables and create private networks for each connection (10.0.0.0/30 and 10.0.0.4/30). The following diagram shows the topology Management Management Management...

Hi! I am about to deploy a virtualisation cluster based on a storage server with 10 Gbps interfaces for iSCSI and two computing nodes running VMs in KVM that will access the storage via the 10 Gbps network. I am trying to find real use cases of people using CentOS 6 as an iSCSI target but can't find any. Anyone using a configuration similar to this one? Thanks in advance! Migue...

...from netback to net front is segmented into MTU size? Is GRO not supported in the guest? I am seeing extremely low throughput on a 10Gb/s link. Two linux guests (Centos 6.4 64bit, 4 VCPU and 4GB of memory) are running on two different XenServer 6.1s and iperf session between them shows at most 3.2 Gbps. I am using linux bridge as network backend switch. Dom0 is configured to have 2940MB of RAM. In most cases, after a few runs the throughput drops to ~2.2 Gbps. top shows that the netback thread in dom0 is having about 70-80% CPU utilization. I have checked the dom0 network configuration and there...
