I have HP DL360p Gen8 646902-xx1 I'm trying to optimize my config for low latency trading.

Should I enable "Intel NIC DMA Channels"? Will that help/affect my system?

From HP doc:

Added a new ROM Based Setup Utility (RBSU) Advanced Performance Option menu that allows the user to enable Intel NIC DMA Channels (IOAT). This option is disabled by default. When enabled, certain networking devices may see an improvement in performance by utilizing Intel's DMA engine to offload network activity. Please consult documentation from the network adapter to determine if this feature is supported.
