As i expected, the sixtrack slowdown is entirely in global-alloc, in daten.f with -fno-tree-promote-statics global alloc : 0.23 ( 4%) usr 0.00 ( 0%) sys 0.24 ( 3%) wall 448 kB ( 3%) ggc without: global alloc : 375.96 (83%) usr 5.00 (62%) sys 453.83 (82%) wall 10714 kB ( 5%) ggc Cute, no? It just has a lot more variables to deal with now that they aren't statics that live in memory (a lot of things now get SRA'd that didn't before, etc).
