Webb7 sep. 2024 · The Linux kernel file cache generally will perform considerably faster than an SSD (or NVMe) based dm-cache device - physical RAM is still significantly faster than solid state drives. However, an SSD based dm-cache can survive a server reboot and should not be as ephemeral as the Linux kernel file cache. WebbEach cached entry uses slightly more than 320 bytes of memory. The DDT code relies on ARC for caching the DDT entries, such that there is no double caching or internal fragmentation from the kernel memory allocator. Each pool has a global deduplication table shared across all datasets and zvols on which deduplication is enabled.
