Hi all,
I'm trying to investigate strange memory consumption, but.
Tested data is 100kb json text.
Tested script:
Empty case:
So expected result for main case will be empty case + data * count_times and it should be something like 35360Kb + 100Kb * 10 ~~ 37Mb
Main case:
Actual result is 270Mb.

Why memory consumption is so HUGE? Why is so different?
I'm trying to investigate strange memory consumption, but
I have no explanation
Tested data is 100kb json text.
Tested script:
var fs = require('fs');
var data = fs.readFileSync(__dirname + '/' +'chartype.letter.json', 'utf8');
var p0 = JSON.parse(data);
var p1 = JSON.parse(data);
var p2 = JSON.parse(data);
var p3 = JSON.parse(data);
var p4 = JSON.parse(data);
var p5 = JSON.parse(data);
var p6 = JSON.parse(data);
var p7 = JSON.parse(data);
var p8 = JSON.parse(data);
var p9 = JSON.parse(data);
Empty case:
/usr/bin/time -f "%MKb" ./node empty.js
35360Kb
So expected result for main case will be empty case + data * count_times and it should be something like 35360Kb + 100Kb * 10 ~~ 37Mb
Main case:
/usr/bin/time -f "%MKb" ./node bench.js
276672Kb
Actual result is 270Mb.
