how to measure bandwidth from host to iscsi san

[marshallmathers]

we have 2 hosts with 10 gig iSCSI links to SAN . (2 per host , jumbo frames enables , no teaming, isolated vlan)

We are receiving reports of slow read speeds (at the VM level)  after upgrade.

What is the best / most accurate way that i can measure the throughput of the VM to the SAN?

Thanks

1 question.

Are you sure that jumbo frames are enabled at the physical switch?

It´s normal to enable jumbo frames in vswitch but no in physical switch

[marshallmathers]

yes 100%

upgraded the iSCSI to 10 gig .

installed 10 GIG network adapter in esxi server.

The most common is using the esxtop command
