High Performance Mode

To run Tenable Network Monitor in High Performance mode, you must enable HugePages support. HugePages is a performance feature of the Linux kernel and is necessary for the large memory pool allocation used for packet buffers. If your Linux kernel does not have HugePages configured, Tenable Network Monitor automatically configures HugePages per the appropriate settings. Otherwise, if your Linux kernel has defined HugePages, refer to the Configuring HugePages instructions in the Linux Command Line Operations section.
