When Rad=1, my scene renders in 1 minute.
When Rad=2, it takes almost 3 minutes!
What is wrong?  Isn't it supposed to be faster?

-----------------------------------
#declare Rad = 1;

global_settings {
  assumed_gamma 1
#switch (Rad)
 #case (1)
  radiosity {
    pretrace_start 0.08
    pretrace_end   0.02
    count 50
    error_bound 0.5
    recursion_limit 1
    save_file "Filename.rca"
  }
 #break
 #case (2)
  radiosity {
    pretrace_start 1
    pretrace_end   1
    always_sample off
    load_file "Filename.rca"
  }
 #break
#end
-----------------------------------
