Hello list, I have two differents installation Xen Hypervisor on two identical physical server, on the same switch : The problem is on my new server (Xen 4.0.1 with pvops kernel 2.6.32.24), I have bad performance on bandwidth I have test with a files copy and "iperf". Result iperf average: Transfert Bandwidth XEN-A -> Windows Physical: 1005 MBytes 843 Mbits/sec XEN-B -> Windows Physical: 522 MBytes 438 Mbits/sec Windows Physical -> XEN-A: 477 MBytes 399 Mbits/sec Windows Physical -> XEN-B: 175 MBytes 146 Mbits/sec It's the same network card but on the new installation, the module bnx2 have a new version... Maybe i haven't activate or forget something... If you have an idea, I listen you !! Thanks in advance ! This is the details of two installations: XEN-A: - XEN 3.2.1 kernel 2.6.26-2-xen-amd64 #xm info release : 2.6.26-2-xen-amd64 version : #1 SMP Sun Jun 21 08:09:04 UTC 2009 machine : x86_64 nr_cpus : 4 nr_nodes : 1 cores_per_socket : 2 threads_per_core : 1 cpu_mhz : 1995 hw_caps : bfebfbff:20100800:00000000:00000140:0004e33d:00000000:00000001 total_memory : 24570 free_memory : 918 node_to_cpu : node0:0-3 xen_major : 3 xen_minor : 2 xen_extra : -1 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_scheduler : credit xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailable cc_compiler : gcc version 4.3.1 (Debian 4.3.1-2) cc_compile_by : waldi cc_compile_domain : debian.org cc_compile_date : Sat Jun 28 09:32:18 UTC 2008 xend_config_format : 4 #lspci -v 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) Subsystem: Dell Device 01b2 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16 Memory at f4000000 (64-bit, non-prefetchable) [size=32M] Capabilities: [40] PCI-X non-bridge device Capabilities: [48] Power Management version 2 Capabilities: [50] Vital Product Data <?> Capabilities: [58] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Kernel driver in use: bnx2 Kernel modules: bnx2 #ethtool -i peth0 driver: bnx2 version: 1.7.5 firmware-version: 2.9.1 bus-info: 0000:05:00.0 XEN-B: - XEN 4.0.1 kernel pvops 2.6.32.24 #xm info release : 2.6.32.24 version : #1 SMP Thu Oct 14 10:56:13 CEST 2010 machine : x86_64 nr_cpus : 4 nr_nodes : 1 cores_per_socket : 2 threads_per_core : 1 cpu_mhz : 1995 hw_caps : bfebfbff:20100800:00000000:00000940:0004e33d:00000000:00000001:00000000 virt_caps : hvm total_memory : 24570 free_memory : 10 node_to_cpu : node0:0-3 node_to_memory : node0:10 node_to_dma32_mem : node0:9 max_node_id : 0 xen_major : 4 xen_minor : 0 xen_extra : .1 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_scheduler : credit xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailable xen_commandline : loglvl=all guest_loglvl=all sync_console console_to_ring com1=19200,8n1 console=com1 cc_compiler : gcc version 4.3.2 (Debian 4.3.2-1.1) cc_compile_by : root cc_compile_domain : test.com cc_compile_date : Thu Oct 14 03:37:34 EDT 2010 xend_config_format : 4 #ethtool -i peth0 driver: bnx2 version: 2.0.2 firmware-version: 2.9.1 bus-info: 0000:05:00.0 #lspci -v 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) Subsystem: Dell Device 01b2 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 1245 Memory at f4000000 (64-bit, non-prefetchable) [size=32M] Capabilities: [40] PCI-X non-bridge device Capabilities: [48] Power Management version 2 Capabilities: [50] Vital Product Data <?> Capabilities: [58] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable+ Kernel driver in use: bnx2 Kernel modules: bnx2 _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
