Hello! I just started testing jemalloc to see if we could improve our memory usage on Xbox & PS3. What would be the best way to configure jemalloc for such "low-memory" platforms ?
I changed lg_chunk to 19... I'm considering reducing the number of arenas (currently at 12). Or maybe disabling thread caching. We typically have very few threads making allocations (< 15), and most of them are alive for the whole duration of the game. But their usage of the memory system differs a lot and in some cases I seem to waste arena space if two memory hungry threads ends up in the same arena. Can I expect good result if I use a single arena ? Did anyone experiment with jemalloc in a similar situation ? I fear disabling all those options will turn jemalloc into an average allocator... Thanks! Sebastien _______________________________________________ jemalloc-discuss mailing list [email protected] http://www.canonware.com/mailman/listinfo/jemalloc-discuss
