			Any server areas allocated above the bar (swappable (<var>[[SERVGA parameter\|SERVGA]]</var>) or non-swappable (<var>[[SERVNSA parameter\|SERVNSA]]</var>)) will be allocated using 1MB pages. This improves LTB (look-aside translation buffer) hits by reducing the number and size of segment and page translation tables, resulting in a performance improvement for the Online.
