...not reliable. The last issue make it impossible to serve VM disk image from the nas. Anybody has met the same issue? Benchmark details below: 1. iperf bench against external host (through physical network). The bench can fully utilize the Giga-bit network. ext => nas ~930Mbps nas => ext ~ 900Mbps TSO / LRO config has no impact on the bench result. 2. iperf bench against dom0 (through virtual bridge, handled fully by driver stack) The bench result highly depends on TSO / LRO config. dom0 => nas (LRO=1) 60Mbps ~ 300Mbps (vary a lot time to time, xentop reports low cpu usage in both domain...

...(pfifo, size 1000 packets ) : flow 1 priority 2 queue (pfifo, size 1000 packets ) : flow 2 priority 3 queue (pfifo, size 1000 packets ) : defaults I configured PRIO qdisc on Router A''s outer interface to Router B. the results of test - TCP throughput about 80Mbps - UDP throughput about 900Mbps. (UDP try to send 1Gbps) First question: The TCP stream with higher priority than UDP stream with lower priority experienced starvation in stead of UDP stream. Is it correct? Did you test PRIO qdisc with TCP having high priority and UDP having low priority? In the below, there is my configurati...

...ware RAID10, 4GB RAM and a quad-core Intel Xeon processor. It's not live yet, so there's no load from other tasks. I've already eliminated the RAID (able to sustain 130-140MB/s for reads/writes) and the network (GigE, tar | nc to this server and untar'd at the other end sustains 8-900Mbps) as bottlenecks, which leaves me dealing with Samba. Samba is peaking at around 280Mbps (reading and writing a single 500MB file) and normal performance (which I have benchmarked with a 350MB directory containing about 1,000 files of various sizes up to 2MB) is closer to 90-100Mbps (write), 117Mbp...

Hi, I am running a VOIP application on Centos 5.3. It is a 16 core box with 12 G of mem and all what it does is passing packets. What happens is that at around 2K channels running g711 ( 64k) codec, all eth0 is used up and no more traffic can go through. I have checked google and it talked about interrupt scheduler. does anyone know how to configure the kernel to allow it to use all CPSs for

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
