如何在$ _SESSION中存储数据与memcache(d)不同?

The obvious difference is that when stored in memcache(d) data becomes available cross the system. Sessions store data per user, though, session_id() could theoretically be used to share this data with more users.

However, in terms of performance, speed and memory usage - is there a difference?
