-XX:+UseLargePages (default false)
Enable the use of large page memory. The goal of the large page support is to optimize processor Translation-Lookaside Buffers (TLB) and hence increase performance.Large pages might be suitable for intensive memory applications with large contiguous memory accesses.Large pages might not be suitable for (i) short-lived applications with a small working set or for (ii) applications with a large but sparsely used heap.Note: consider enabling large pages when the number of TLB misses and TLB Page walk take a significant amount of time (i.e. dtlb_load_misses_* CPU counters).
