That memory can be swapped to disk doesn't really mean that you should never intentionally move data to disk in an application.
The application can (at least theoretically) know things about usage patterns that the virtual memory subsystem cannot know. Performance tuning of this nature _is_ difficult and fiddly, and it is difficult to know ahead of time whether this particular approach would help or hurt.
