Yes it does.  

Tips for optimizing the agenda speed can be found here:

But I'm not sure it will help in this case.

[O] question about performance when having multiple todo blocks from the same org files ..

[Rainer Stengele]

Hi.

I have a complex agenda function as can be seen below.
Beside an agenda call I do want to show todos separated in blocks, grouped by 
priority or tags.
I want to show my prio A todos as one block before showing the rest of the 
todos sorted by prio.
I was wondering if Org does run through all the org files again and again in 
order to collect the data wanted
or if there is something like a cache is being filled when running through all 
buffers, collects all todos and then groups, sorts
and is availble for printing out whats wanted.

Thank you for a reply from someone who knows the internals.

Rainer
