Expected Behavior

Currently not supported/enabled

  2. See that it can't use them
  3. Notice how performance is poor :(

Specifications

  • Version (using nerd version): 0.5.9
  • Platform: N/A

Anything else we need to know?

Huge pages are virtual memory pages which are bigger than the default base page size of 4KB. Huge pages can improve memory performance for common access patterns on large data sets. Huge pages also increase the maximum size of data and text in a program accessible by the high speed network.

Seems to me that's a legitimate use case here :)

And related: ulimit -l is set to 64MB max, so that should probably also be either adjustable or set to the allowed memory consumption size of the workload?
