Improve the records processing time

Now it iterates over the same enumerable multiple times without need
which in low records size object is not a big deal but in our case
it takes a considerable amount of time to do it:

Records count: 207
  0.000000   0.010000   0.010000 (  0.002049)
  0.000000   0.000000   0.000000 (  0.002214)
  0.000000   0.000000   0.000000 (  0.001979)
  0.010000   0.000000   0.010000 (  0.002516)
  0.000000   0.000000   0.000000 (  0.002142)
Records count: 142191
  2.050000   0.180000   2.230000 (  2.224884)
  2.090000   0.090000   2.180000 (  2.176774)
  2.050000   0.080000   2.130000 (  2.124951)
  2.140000   0.100000   2.240000 (  2.249662)
  2.040000   0.100000   2.140000 (  2.157886)

  ### NEW METHOD

  0.000000   0.000000   0.000000 (  0.001829)
Records count: 142191
  1.050000   0.000000   1.050000 (  1.056097)
  1.040000   0.000000   1.040000 (  1.034397)
  1.020000   0.010000   1.030000 (  1.018424)
  1.100000   0.000000   1.100000 (  1.103647)
  1.030000   0.000000   1.030000 (  1.032034)

I've also check the objects allocation and are the same so its worth to
change how this is done
