Are memory benchmarks supposed to be stable? I tried running multiple times and it seems like the memory usage varies quite a bit. For releases, we’re running it 5 times and taking the min.
Memory should be pretty stable (unless GC triggered a heap growth that can happen), try inside docker, then outside docker (just try reproing numbers for 2.2.0)
need exact script you are running and can you confirm the meaning of the numbers.
ps -o rss= -p #{pid}. According to man ps: rss RSS resident set size, the non-swapped physical memory that a task has used (inkiloBytes). (alias rssize, rsz).
