Environment Variables

You can override some of the constants used by Foundation using environment variables:

Maximum size of unpinned arrays (in bytes)

  • Default: 1024

When memory for a new array is allocated, we decide if that memory region should be pinned (will not be copied around by GC) or unpinned (can be moved around by GC) depending on the size of the memory region. This value specifies up to which size unpinned memory will be used.
