Sorry, performance problems in EXA - which is still clearly marked as 
experimental - are simply not going to hold up 7.0.  In fact at this point 
unless EXA is actively misrendering or crashing on you it's unlikely any 
changes will be made to it before 7.0.

Not that that's a big deal; releases in a modular world are much easier, so as 
performance fixes are made they will get released pretty quickly.

In general, statements like "EXA is slow for me", even when describing a use 
case, are not sufficient information to determine where the slowdown is 
occuring.  At a minimum, use a profiling tool like sysprof or oprofile to get 
some actual numbers on what code paths are being hit most.

If you're looking for a more interesting challenge, it would be a neat hack if 
the server could collect its own statistics on the runtime of various X 
requests.
