Compressed Memory Overhead

Post by MemoryHog »

Most hard drives these day are using the more efficient 4kb sector advance format, so it is obvious that if the hard drive was formatted with a 4kb allocation unit size, the ssd L2 cache block size should match that for the fastest possible operation. However, setting a 16 gig l2 cache size with 4kb block size results in a gargantuan 4 gigs of physical memory usage for memory overhead. With the advent of windows 10 using compressed memory, would it be possible to compress (and decompress on the fly) the L2 memory overhead as well?

The compression/decompression way will affect the cache performance a lot. So I don't think we'll use this method. But we do work to reduce memory overhead.
