when using the bundle with activated big enough cache, very slow and wasteful memory allocations lead to jittery playback and lot of dropped frames. the cache had to have a certain size so it would constantly allocate new memory to reproduce this. this never happens when started from the terminal. the source of the problem is a different malloc allocation policy, MALLOC_NANO, that allocated a huge amount of virtual memory without actually using it. the usage was between 0% to 25% of that virtual memory. the binaries allocation policy on the other hand used >80% of that allocated virtual memory and was a lot more efficient, it would use MALLOC_TINY instead. this is fixed by setting the MallocNanoZone environment variable to 0 to use the V1 of the allocation policy. when started from the bundle via launchd this is forced to 1 and V2 policy which causes this problem. some more info can be found in following file and its comments on the Apple open source site: https://opensource.apple.com/source/libmalloc/libmalloc-317.40.8/src/nano_malloc_common.c.auto.html Fixes #7405 |
