As I said. Mathed is essentially uchanged since 1.2.0. It was completely different before, but speed was acceptable in the 1.2.x and 1.3.x series. So whatever triggers that behaviour is some recent interaction. Note that I am not saying the data model is perfect, especially since I changed my stance about reference counting and deep copies vs COW lately. > I guess this could be related to the data memory models used in mathed. > Maybe some big tables created/deleted on the fly?
