How involved is your user model and what type of machine do you have?

I'm on an 8 year old i5 3.2ghz CPU based workstation running in WSL 2 with Docker.

With Rails 7.0.4 and Ruby 3.2.1 (YJIT not enabled):

1M empty hashes:

    Benchmark.measure{1000000.times{Hash.new}}
    @total=0.192643

But in 0.192 seconds I'm able to make 12,500 user models:

    Benchmark.measure{12500.times{User.new}}
    @total=0.19225799999999982

That is over 6,000 more than your ratio but based on your first number something tells me you have a much faster dev box than me.
