Antoine Pitrou asked me to document the performance and memory overhead of -X dev: https://mail.python.org/pipermail/python-dev/2017-November/150578.html For example, I measured an increase of +50% on the peak memory usage (measured by tracemalloc) when running test_os. Antoine proposed: """Currently, developer mode adds negligible CPU time overhead, but can increase memory consumption significantly if many small objects are allocated. This is subject to change in the future.""" https://mail.python.org/pipermail/python-dev/2017-November/150579.html
