Content
So this test script is making a 65K entry dict, and each item is a new, separate 65K string. The strings are allocated in single chunks, so we should expect couple hundred reference count writes total. AIUI involuntary context switches occur when there is CPU contention. What else do you have running? Notable Python is taking 3.83 seconds of system time, much more than your other tests. You may get some insight from strace -c.
