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.
