VMware takes advantage of many of the performance features from modern network adapters.
In this section, we are going to talk about two of them and they are:
- TCP checksum offload
- TCP segmentation offload
To step through this recipe, you will need a running ESXi Server with SSH enabled and an SSH client (Putty). No other prerequisites are required.
The list of network adapter features that are enabled on your NIC can be found in the /etc/vmware/esx.conf
file on your ESXi Server. Look for the lines that start with /net/vswitch
.
However, do not change the default NIC's driver settings unless you have a valid reason to do so. A good practice is to follow any configuration recommendations that are specified by the hardware vendor. Carry out the following steps in order to check the settings:
- Log in to the ESXi host using an SSH client (Putty).
- Open the
etc/vmware/esx.conf
. file. - Look for the line that starts with
/net/vswitch
.
- Your output...
