I have a python fast API service. I see that the railway metrics is showing RAM always higher than 500MB.

But when I added log statement in my service, it shows 100MB

Python code: print("Memory (MB):", psutil.Process(os.getpid()).memory_info().rss / 1024 ** 2)

This 500MB metric is always consumed irrespective of traffic. I want to know what i am missing here?

Thanks, in advance!
