    initial v1  
    4444(Perf test case is also in the PR.)
    4545
    46 What sticks out is the fact, that `bulk_update` is even so much worse than plain `update` chaining. Which makes me wonder what was its actual use case in first place and reason to add it to django core?

     48Edit: This might be partially a local (TM) artifact, a LAN-connected DB would adds its roundtrip latency on top that. Could also be that sqlite & postgres got much better in handling a flood of update statements. (At least sqlite does not show anymore that weird perf decline around 5k instances with `bulk_update` it had 3 years ago.)
