vSphere Broadcom performance issue

Hi all

My configuration: 2 x HPDL 380 G5, vSphere Standard, vCenter Foundation, MSA1000

Both servers are equipped with 1 HP NC373i Multifunction Gigabit Server Adapter (embedded - 2 ports) and 1 HP NC360T (added - 2 ports). The first is identify by ESX as Intel Corporation 82571EB Gigabit

Ethernet Controller and the second as Broadcom Corporation Broadcom

NetXtreme II BCM5708 1000Base-T. The NIC are connected to the same Gb switch.

When I copy a test file (1GB) from a physical server to a VM (Windos 2003) that is "binded" to the Intel NIC, performance are 40-42 MB/s. The same test from the same server to other VM (Windows 2003, XP, Linux) performs 20-22 MB/s.

Maybe a IRQ or a driver problem ?

cat /proc/vmware/interrupts (Broadcom are vmnic0 and vmnic1)

Hello Max,

we are facing the same problem on a broadcom adapter here. Did you resolve the problem?

Best regards,
