If you're using Git for SCM, then you can reduce the polling significantly using a post-receive hook in your git repositories. See [1] for more information
If you're keeping a long job history, you can reduce memory requirements by reducing the amount of history you are retaining. Later long term support versions (after 1.480.2, like 1.509.3) now support lazy loading of build records which reduces memory requirements. Refer to [2] for more information.
