Description:
------------
I'm using serialize()/unserialize() very active for storing/retrieving objects to/from memory (using memcached/xcache). The main problem is performance: unserialize() takes very much time and finally caching comes not very effective. This is not version-related problem, I'm expecting on all 4/5 versions. Unfortunately there is now way to share objects between PHP processes without serialize()/unserialize(). I just want draw your attention to made unserialize() faster... or create a way to share data between PHP processes without using serializing at all. I think optimizing unserialize() should be easier. Thank you.

Is this still an issue? json_decode() (for JSON-encoded data) may be faster as it doesn't need to check for references.
