UnverifiedLakebase's local file cache is a layer of local SSD/memory cache situated between shared buffers and remote object storage within its cloud-native storage architecture, and is not the OS page cache of standard Postgres.65% similarUnverifiedCU ≥ 80 corresponds to large instances with memory on the order of hundreds of gigabytes in Lakebase's specification system.64% similarUnverifiedvLLM's PagedAttention splits the KV cache into fixed-size physical blocks (typically 16 tokens), improving GPU memory utilization from below 40% to close to 90%.63% similarUnverifiedTraditional KV cache implementations pre-allocate contiguous GPU memory blocks of maximum length, resulting in an average of 60%–80% of pre-allocated memory being wasted.61% similarUnverifiedDisabling file caching eliminates double-caching waste, but once data misses shared buffers it goes directly to the storage layer, requiring a sufficiently high hit rate; otherwise the cost of a miss may be amplified.59% similar
