What should my transmit buffers be?
Look for ‘Receive Buffer’ and ‘Transmit Buffer’ in the list. The recommended size is either 512 or maybe even 1024 – you can go up to 2048 if you have enough RAM to support it. Ensure that the transmit buffer is double the receive buffer. Just remember, that going below 256 will lead to dropped packets.
What does transmit buffers mean?
buffer size of system
Transmit Buffers: The buffer size of system memory that can be used by the adapter for sending packets, which can be increased to help improve the performance of outgoing network traffic, but it consumes system memory.
Should I disable auto disable gigabit?
When users change the setting to Re-Link and user unplugs and plugs network cable again, the driver will automatically disable gigabit capability. Gigabit has much higher power consumption than 10/100 MBps. For notebook users, it is recommended to turn on this to reduce power consumption.
Should I disable Flowcontrol?
Should you completely disable flow control on all computers and switches? Not necessarily. It is generally safe to leave flow control enabled on computers. Switches, though, should either have flow control disabled or configured such that they will honor received pause frames but will never send out new pause frames.
Should I disable Large Send Offload?
Large Send Offload is a technique of improving network performance while at the same time reducing CPU overhead. Apparently it does not work very well, so it was suggested to disable it. If you would like to know about LSO, check this MSDN article from 2001 (Task Offload (NDIS 5.1) (Windows Drivers)).
Should I disable Priority & VLAN?
Priority & VLAN is automatically enabled when you set up a VLAN on the VLAN tab. You cannot disable tagging because tagging is required for VLANs….Advanced Driver Settings for Intel® Ethernet 10 Gigabit Server Adapters.

Is flow control good?
Using Flow Control is typically not a good recommendation and is rarely used. This is because flow control can cause head of line blocking across ports and queues. For example, priority 0 buffer is full, so the switch sends a pause frame to the transmitter on the side of the link.
Is flow control bad?
This situation is called head-of-line blocking, and it is the major reason why Ethernet flow control is somewhat dangerous to use. When enabled on network switches, it can create situations where one slow link in a network can bring the rest of the network to a crawl.
