:mrdocs:

Create an instance of this class that uses the specified `scheduler` to automatically collect performance statistics every specified `interval` (specified in seconds). Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. A non‐positive `interval` value indicates that performance statistics should _not_ be automatically collected‐‐in this case the user is responsible for manually calling the `collect` function.
