The MEMPROF_HASH_BITS variable was set to 10 without a possibility to change it (beyond patching the code). After seeing a few reports already with "other" being listed and a list with close to 1024 entries, it looks like it's about time to either increase the hash size, or at least make it configurable for special cases. As a reminder, in order to remain fast, the algorithm searches no more than 16 places after the hash, so when a table is almost full, searches are long and new places are rare. The present patch just makes it possible to redefine it by passing "-DMEMPROF_HASH_BITS=11" or "-DMEMPROF_HASH_BITS=12" in CFLAGS, and moves the definition to defaults.h to make it easier to find. Such values should be way sufficient for the vast majority of use cases. Maybe in the future we'd change the default. At least this version should be backported to ease rebuilds, say, till 2.8 or so. |
