QPI Bandwidth Optimization (RTID)
NOTE: This option is available on Gen8 servers with Intel processors.
The QPI link between two processors has been tuned to provide the best performance for all known
applications.
Options include:
• Balanced (default)—Provides the best performance for nearly all conventional customer
applications and benchmarks.
• Optimized for I/O—Increases bandwidth from I/O devices such as GPUs that rely on direct
access to system memory. This setting can have a negative effect on system performance.
NOTE: Setting this option to Optimized for I/O can have a negative impact on memory and
system performance.
