Memory deduplication techniques aim to reduce memory consumption by sharing redundant memory pages. Additionally, hugepages are commonly employed to optimize performance by minimizing TLB misses. However, the simultaneous use of memory deduplication and hugepages presents a technical challenge. Existing approaches either split hugepages to achieve efficient memory deduplication or overlook redundant portions within hugepages to maintain high performance. As a result, they are compelled to compromise either performance or memory utilization.
