Low Latency Tweaking

Recommended Posts

Good guide for tweaking your Ethernet Card (NIC)

May help some with stabilizing your ping & packet loss


Also added this to the help guides section


This by the author if you dont want to bother with the tech details...

In case you were wondering what settings I recommend generically:

ARP Offload - Disabled
** Auto Disable Gigabit - Disabled ** - will deny gigabit capable users auto-negotiated gigabit
* Energy Efficient Ethernet - Disabled * -
** Flow Control - Disabled **
** Green Ethernet - Disabled ** -
** Interrupt Moderation - Disabled ** (Even MS says turn this off for low latency)
* IPv4 Checksum Offload – Disabled *
Jumbo Frame - Disabled
** Large Send Offload v2 IPv4 - Disabled ** (affects net like IM, according to sys-admin blog)
** Large Send Offload v2 IPv6 - Disabled ** 
Maximum Number of RSS Queues – X - does nothing with RSS disabled
Network Address - Not Present
NS Offload - Disabled
Priority & VLAN - Disabled
Receive Buffers - 512 (MAX Setting)
** Receive Side-Scaling – Disabled ** - NEEDS RESEARCH
Speed & Duplex - Auto Negotiation
* TCP Checksum Offload IPv4 – Disabled *
* TCP Checksum Offload IPv6 – Disabled *
Transmit Buffers - 128
* UDP Checksum Offload IPv4 – Disabled *
* UDP Checksum Offload IPv6 – Disabled *
Wake on Magic Packet - Disabled
Wake on pattern match - Disabled
WOL & Shutdown Link Speed - Not Speed Down

The ** marked settings are the main culprits consistent across test subjects.
The * marked settings are one’s that you'll most want to experiment with.

An interesting note; with one router, I got a better performance with the Checksum Offloads being on and when I replaced it with a more recent one, the same settings offered a degraded performance. This was fixed for the new router by turning off Checksum Offloads.

The point being… experiment! The whole configuration can be sensitive to changes at any point from the computer drivers, down the cables and out to router hardware.
