Performance Tuning • Maximum performance
(default)
• Dynamically balanced
• Statically balanced
Windows Server 2012 This parameter selects the driver
algorithm for performance tuning,
allowing you to balance raw
networking throughput with
overall system fairness among
multiple devices and applications.
• Maximum Performance - This
mode maximizes the network
performance for this adapter.
This is the recommended
mode. However, in systems
with a large number of network
or storage adapters, this mode
may limit the performance of
other devices.
• Statically Balanced - This mode
configures the network adapter
to throttles CPU usage in all
cases, allowing more balance
among hardware devices and
applications. If system
responsiveness is poor, this
mode may improve the overall
system behavior.
• Dynamically Balanced -
Dynamic balancing adjusts the
network adapter's performance
based on system metrics, such
as CPU usage. This mode can
aggressively limit performance
for the most stressful
networking applications to
ensure that all network
adapters can share limited
computer resources, yet it can
maintain maximum
performance when the system
has resources available.
