Someone else brought up the recent podcast episode of CoRecursive. One benefit that was brought up was compression of the cache close to the user’s physical location. Facebook has a lot of machines around the world dedicated to this sort of cache. They need a balance between compression ratio and compression/decompression throughput. There’s no point using a great compression algorithm to achieve an amazing compression ratio if you end up being CPU-bound when you need to decompress it later on.
