When I run top I see (uWSGI using ~860MB of RES; this is in Docker): PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 11 root 20 0 1048736 360688 19064 S 0.3 17.6 1:17.00 uwsgi 12 root 20 0 1018840 328140 18964 S 0.3 16.0 1:42.41 uwsgi RES stands for the resident size, which is an accurate representation of how much actual physical memory a process is consuming. I would like to understand what is using that much RAM. I tried to use the standard Python heap analysis tools however they don't reveal anything that large. For example using pympler, I see: types | # objects | total size ============================ | =========== | ============ dict | 7933 | 9.15 MB str | 50742 | 8.40 MB code | 18044 | 2.20 MB type | 2347 | 2.03 MB unicode | 3188 | 1.56 MB tuple | 8012 | 588.46 KB list | 4425 | 550.81 KB weakref | 3707 | 318.57 KB set | 828 | 308.59 KB builtin_function_or_method | 3432 | 241.31 KB cell | 3267 | 178.66 KB function (__init__) | 1417 | 166.05 KB getset_descriptor | 2337 | 164.32 KB wrapper_descriptor | 1968 | 153.75 KB _sre.SRE_Pattern | 290 | 123.77 KB Could there be some sort of off heap memory usage? Perhaps uwsgi itself is using that much RAM?
