WebMar 29, 2014 · It seems both psutil and ps shows RSS to be zero for such processes. The result depends on whether the subprocess will exit sooner than p.memory_info () is called. It is a race. If you add a delay at the exit in the C++ program then p.memory_info () may be called before the subprocess exits and you should get non-zero results. WebSep 10, 2024 · 3 Answers. I think you are misinterpreting the output of psutil.cpu_percent (). Returns a float representing the current system-wide CPU utilization as a percentage.

Psutil memory info

Webpsutil.virtual_memory() (aka system memory) is fine, so we don't need to do anything. The problem is with Process.memory_info() for PIDs not owned by current unprivileged user. psutil already uses host_statistics() for retrieving system mem ( psutil.virtual_memory() ). WebAug 23, 2024 · psutil author here. I doubt other tools can do a significantly better job. Reading /proc/pid/stat is the only way for a user space app to get those process info so all of them (ps, top, etc.) basically do the same thing: read the file and parse it. As such I don’t expect one can be significantly faster than another one.
