From the cobalt memory docs , we set max_cobalt_cpu_usage limit to 250M, max_cobalt_gpu_usage to 150M, and found the actual max memory used by cobalt is about 370M when play the 4K videos for about 12 hours, it exceeded 250M a lot, so what kind of memory(eg. malloc/new/mmap etc.) is counted into max_cobalt_cpu_usage? How to set the max_cobalt_cpu_usage and keep the actual memory usage within the max_cobalt_cpu_usage?

PS.The memory statistical approach is as follows:
1>Move focus to the cobalt icon, drop the memory cache, record the memory free value(memoryBegin) from /proc/meminfo;
2>Enter cobalt youtube, and keep playing 4K videos for about 12 hours;
3>During playing the videos, record the memory free value(memoryEnd) from /proc/meminfo every 10s(drop the memory cache before record the memory);
4>Find the minimum memoryEnd as  memoryEndMin;
5>memoryBegin - memoryEndMin = 370M;

what kind of memory(eg. malloc/new/mmap etc.) is counted into max_cobalt_cpu_usage?

The value returned from SbSystemGetUsedCPUMemory() is used to determine the current cpu memory usage. Please ensure that this returns the expected values.

Note that the cache's won't dynamically re-size to keep within the limits. The initial conditions must be set to account for the maximum memory limit that is required to be set.

You can manually reduce the sizes of your caches (see memory_tuning.md document) or you can use --reduce_cpu_memory_by=Xmb which will allow the AutoSet memory settings to reduce their memory usage.

For more information about memory use, use --memory_tracker as a command line argument.
