python daemons in bookworm are consuming more memory than in bullseye #19828

Open vivekrnv opened 1 month ago

vivekrnv commented 1 month ago

Description

python daemons in bookworm is consuming more memory than in bullseye.

Some daemon like xcvrd, thermatctld, featured, hostcfgd, healthd etc has RSS increased by around ~ 20MB. Even smaller daemons has size increased by "container wait", supervisor-proc-exit-listener by 7 MB.

Combined with new daemons such stormon, dhcprelayd the overall mem usage will be higher by atleast ~500 MB. On a system with 8GB RAM this would account to almost 5-6 % more usage. Thus the test_cpu_memory_usage.py test should be updated to handle the increase.

This is happening because of speed optimization made for python 3.11 https://devclass.com/2022/05/31/how-python-3-11-is-gaining-performance-at-the-cost-of-a-bit-more-memory/

and seems this optimization has some memory implications https://peps.python.org/pep-0659/#memory-use

Steps to reproduce the issue:

  1. Run the test_cpu_memory_usage on 202405/master images on devices with RAM <= 8 GB and it will fail https://github.com/sonic-net/sonic-mgmt/blob/master/tests/platform_tests/test_cpu_memory_usage.py#L54

  2. Or just load the image and check memory usage after some time
