MPRester.get_entries_in_chemsys() runs slowly

Hi, not sure if this is just for me, but I am finding that Pymatgen get_entries_in_chemsys is running really slowly. In the past I could retrieve all the entries in a quaternary system in < 5 sec, now it takes minutes. Is there something new in the API slowing the entry retrieval?

Materials Project is currently experiencing heavy load issues due to a large increase in traffic recently, the MP team is working to resolve this.
