Perbandingan kinerja pemrosesan karakter antara node.js dan php dan python

Kasus uji dibagi menjadi fungsi dan kelas untuk membaca karakter string besar satu per satu.

Kode uji

Node.js

fungsi

 var fs = membutuhkan ("fs"); var content = fs.readfileSync ("page.html", {encoding: "utf-8"}); function chars (content) {var length = content.length; var pos = 0; while (pos ++ <panjang) {var chr = konten [pos - 1]; }} var start = date.now (); chars (konten); var end = date.now (); console.log (end - start);

baik

 var fs = membutuhkan ("fs"); var content = fs.readfileSync ("page.html", {encoding: "utf-8"}); var chars = fungsi (str) {this.str = str; this.length = str.length this.pos = 0;} chars.prototype.run = function () {while (this.pos ++ <this.length) {var chr = this.str [this.pos - 1]; }} var start = date.now (); var instance = chars baru (konten); instance.run (); var end = date.now (); console.log (end - start);

Php

fungsi

 <? phpfunction chars ($ content) {$ length = strlen ($ content); $ pos = 0; while ($ pos ++ <$ length) {$ char = $ content {$ pos - 1}; }} $ content = file_get_contents ("page.html"); $ start = microtime (true); chars ($ content); $ end = microtime (true); echo ($ end - $ start). "/n";?>

baik

 <? phpclass chars {fungsi publik __construct ($ str) {$ this-> str = $ str; $ this-> length = strlen ($ str); $ this-> pos = 0; } fungsi publik run () {while ($ this-> pos ++ <$ this-> length) {$ char = $ this-> str {$ this-> pos-1}; }}} $ content = file_get_contents ("page.html"); $ start = microtime (true); $ instance = chars baru ($ content); $ instance-> run (); $ end = microtime (true); echo ($ end - $ start). "/n";?>

Python

fungsi

 import codecsimport timedef chars(content): length = len(content) pos = 0 while(pos < length): char = content[pos] pos = pos + 1f = codecs.open('page.html', encoding='utf-8')content = f.read()start = time.time()chars(content)end = time.time();print end - start

baik

 Impor CodecSimport TimeClass Chars (): def __init __ (self, str): self.str = strand self.length = len (str) self.pos = 0 def run (self): while (self.pos <self.length): char = self.str [mandiri] self.pos = self.pos + 1f = codec.pos.pos] self.pos = self.poss + 1f = codec. encoding = 'UTF -8') konten = f.read () start = time.time () instance = chars (konten) instance.run () end = time.time (); print (end - start)

Konten file page.html adalah teks panjangnya.
