Mysql6 or Mysql5

[Grant Peel]

Hi all,

I am asking thise here as I am aware there are many ISPs and Hosting farm admins on this list.

I am in the process of setting up the next gen servers, and notice the Mysql6 is available in ports.

Does anyone have any expierience with it? Is it solid? Fast? Are there any 'gotchas' when using databases developed on older versions of Mysql? (4).

Thanks,

-Grant
