description: This option is now a no-op.

Re-map the Node.js static code to large memory pages at startup. If supported on
the target system, this will cause the Node.js static code to be moved onto 2
MiB pages instead of 4 KiB pages.
This option is no longer supported and a no-op. It used to re-map the Node.js
static code to large memory pages at startup.

The following values are valid for `mode`:
It still accepts the following values for compatibility:

* `off`: No mapping will be attempted. This is the default.
* `on`: If supported by the OS, mapping will be attempted. Failure to map will
be ignored and a message will be printed to standard error.
* `silent`: If supported by the OS, mapping will be attempted. Failure to map
will be ignored and will not be reported.
* `on`: No mapping will be attempted and a message will be printed to
standard error stating it's no longer supported.
* `silent`: Same as `off`.

description: This option is now a no-op.

Re-map the Node.js static code to large memory pages at startup. If supported on
the target system, this will cause the Node.js static code to be moved onto 2
MiB pages instead of 4 KiB pages.
This option is no longer supported and a no-op. It used to re-map the Node.js
static code to large memory pages at startup.

The following values are valid for `mode`:
It still accepts the following values for compatibility:

* `off`: No mapping will be attempted. This is the default.
* `on`: If supported by the OS, mapping will be attempted. Failure to map will
be ignored and a message will be printed to standard error.
* `silent`: If supported by the OS, mapping will be attempted. Failure to map
will be ignored and will not be reported.
* `on`: No mapping will be attempted and a message will be printed to
standard error stating it's no longer supported.
* `silent`: Same as `off`.

description: This option is now a no-op.

Re-map the Node.js static code to large memory pages at startup. If supported on
the target system, this will cause the Node.js static code to be moved onto 2
MiB pages instead of 4 KiB pages.
This option is no longer supported and a no-op. It used to re-map the Node.js
static code to large memory pages at startup.

The following values are valid for `mode`:
It still accepts the following values for compatibility:

* `off`: No mapping will be attempted. This is the default.
* `on`: If supported by the OS, mapping will be attempted. Failure to map will
be ignored and a message will be printed to standard error.
* `silent`: If supported by the OS, mapping will be attempted. Failure to map
will be ignored and will not be reported.
* `on`: No mapping will be attempted and a message will be printed to
standard error stating it's no longer supported.
* `silent`: Same as `off`.
