I agree with you in the general case, but in my specific case, I'd 
prefer to configure Emacs Ada Mode in some way to search the 
complementary file in the same directory.

Ideally the search of the Ada file could be done on the search-file 
generated by GNAT using the -C=file switch. This would improve 
performance while preserving the same search path than the compiler. But 
since this problem of mine is not very usual, this is probably asking 
too much.

The problem is the virtual file-system we are using. It's a Clear Case 
dynamic view, and it's really slow on the stat() system call.
