Is it possible to convert a Composite object created with spmd to an array?

Yes, you can use Composite indexing (which behaves pretty much like cell array indexing), like this:
x = labindex;
xlocal = [x{:}]

is there a faster way?
If I read the code correctly, you could use struct() to access private properties of the composite object, and then call some internal routines directly. It would take you a bit of research to figure out which routines to call on which objects, and you might have to shadow the existing class definitions to get access permissions to access the functions.
If I read the code correctly, if you did all of this, then for each composite member access, you would be able to skip one check of whether you are inside a parfor loop. Should be good for about 3 milliseconds per pool member.
