VMWARE host generalist question 😀

Hello experts.
I have a request to update host nic drivers (this bit I can do), and also to 'optimise' the host NICs. What's that mean exactly? could it be referring to network Enhancement features such as RSS and NetDMA perhaps? or is this something that is VMWARE specific and that you vmware experts can point me in the direction of?
thank you for reading.

Is this on the host or the guests ?

and what options do you need to turn on, and are these supported within the Guest or Host ?

It will be VMware specific, e.g. the nic driver needs to support it, and is all configured via VMware ESXi.

e.g. duplex and speed settings could be considered as optimisation!

I would recommend looking into nic firmware as well as drivers.  If using for iSCSI look at queue depth, etc..

Your original question was a bit vague.. :-)
