I'll give it a shot.  Never heard of it before.

There's this

As you can see YAML is indeed slow.  But for session (un) 
serialization its completely unusable.

I did all of my xmlhhtprequest using the JSON pure perl module, and  
felt a big ease on resources when i found that syck module.

Using the syck binding for yaml with session serialization totally  
saved me though.
