Subject: interpreting the second profiling column of Ruby profiler

Hello,

I doubt in interpreting the second profiling column of Ruby profiler.
Here you are a small portion of the profiler's output:

  %   cumulative   self              self     total
 time   seconds   seconds    calls  ms/call  ms/call  name
 12.63   115.42    115.42   268703     0.43     0.63  Array#hash
  7.48   183.72     68.31   160340     0.43     0.64  Array#eql?
  6.06   239.10     55.38   161270     0.34     1.56  Hash#[]
  5.99   293.87     54.77   537406     0.10     0.10  Kernel.hash
  4.29   333.06     39.19    14370     2.73    10.98  FST#del_transition

[...]

  0.00   905.65      0.00        1     0.00 913743.00  #toplevel
  0.00   905.65      0.00        5     0.00     0.00  Module#public
  0.00   905.65      0.00        6     0.00     0.00  Hash#clear
  0.00   905.65      0.00        1     0.00   460.00  Chains2MINFST#finish
  0.00   905.65      0.00        5     0.00     0.00  Hash#new

In "Ruby Developer's Guide", it is written:
"... The second column is the cumulative for the methods up to and including
the current one. ..."

But why the numbers below in the second column are so big?


With the best regards,
Sergei
