which percona to use?

i’m looking to try a new version of mysql, but i’m a little confused about the differences between percona mysql and xtradb.

in order to get the most i/o patches, which should i be looking at?

something else?

i’m assuming there is quite a bit of overlap among these, but i’m having a hard time wrapping my head around it.

Still interesting? )

apparently it was too stupid of a question to answer. i just installed the google patches instead. i’m happy enough with it.
