TCP/IP Full Offload
The DXE-810T does not use Windows Chimney interface, therefore, it is recommended to disable it during
stress-testing:
Command Prompt:
netsh interface tcp set global chimney=disabled
Auto-Tuning
From Windows Vista and on, Microsoft introduced a new TCP management option called Windows Auto-
Tuning. This configuration, which is enabled by default in modern systems, gives Windows OS the
permission to automatically manage TCP connection parameters for better WAN performance.
Administrators should disable this function before stress-testing.
Command Prompt:
netsh interface tcp set global autotuninglevel=disabled

Network Throttling Index
Windows OS implements a restriction mechanism for processing non-multimedia network traffic.
The following registry key configures this index:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Multimedia\SystemProfile NetworkThrottlingIndex=ffffffff (DWORD)
It is recommended to change the default 0x10 to 0xFFFF_FFFF for maximum throughput.

Linux OS
For best results, it is recommended that a fresh copy of the OS and all updates are installed.
Firewall
For uninterrupted benchmark testing, the best practice is to first disable active firewalls. Please follow the
documentation relevant to your Linux distribution to shut down any firewalls.
IRQ SMP Affinity
D-Link network devices use round-robin interrupt allocation method. The system administrator should make
sure that at least 4 cores are allocated in order to service D-Link NIC interrupts.
# echo <hex_bit_mask> > /proc/irq/40/smp_affinity
Note: Administrator will need to define the bit mask.
