It may or may not be a little faster. But the issue is that mem_cache needs to keep a separate copy in memory for each apache process. disk_cache, on the other hand, takes advantage of the OS disk cache buffers, which will probably wind up keeping the files in memory as well. But the OS is smart enough to keep only one copy, and can potentially do zero-copy IO (with sendfile). Add to that the fact that mem_cache seems a little less stable overall, and I think disk_cache is the best choice for most people.
