"perf.py -m" doesn't work with such bash script, but it works using exec: --- #!/bin/sh LD_PRELOAD=/usr/lib64/libjemalloc.so exec /home/haypo/prog/python/default/python "$@" --- > Memory consumption: python3 -u perf.py -m ../default/python ../default/python.jemalloc Hum, it looks like jemalloc uses *more* memory than libc memory allocators.
