Remove code in arena_dalloc_bin_run() that preserved the "clean" state of trailing clean pages by splitting them into a separate run during deallocation. This was a useful mechanism for reducing dirty page churn when bin runs comprised many pages, but bin runs are now quite small. Remove the nextind field from arena_run_t now that it is no longer needed, and change arena_run_t's bin field (arena_bin_t *) to binind (index_t). These two changes remove 8 bytes of chunk header overhead per page, which saves 1/512 of all arena chunk memory. |
