More examples:
Goes from 20mb to 40mb then drops down to 25mb:
var set = {};
var testMemoryUsage = function() {
var length = 1000000;
while (length--) set[length] = 1;
};
Goes from 20mb to 120mb then drops down to 96mb:
var set = {};
var testMemoryUsage = function() {
var length = 1000000;
while (length--) set['s' + length] = 1;
};
Goes from 20mb to 132mb then drops down to 113mb:
var set = {};
var testMemoryUsage = function() {
var length = 1000000;
while (length--) set[Math.random()] = 1;
};
Something's not right if it takes 90mb to store 19mb (in the case of
the Math.random example) of data in a hash table.
