Doing some tests on windows with node v0.8.11
--------------------------------------------
var buf = new Buffer(10000000);
buf.fill(0xFF);
var len = buf.length;
var a;
var start = new Date();
for(var b = 0 ; b < len; b++){
a = buf.readUInt8(b);
}
var end = new Date();
console.log('Buffer reads ' + (end - start) + ' ms'); // Prints 81ms
------------------------------------------------
var arr = [];
var len = 10000000;
for(b = 0 ; b < len; b++){
arr[b] = 0xFF;
}
var len = arr.length;
console.log(len);
start = new Date();
for(b = 0 ; b < len; b++){
a = arr[b];
}
end = new Date();
console.log('Array reads ' + (end - start) + ' ms'); // Prints 29ms
And I always thought that buffers would be faster than arrays in node.js ?
:(
Am I doing something wrong ??
