我的测试环境

CPU:     4核 Intel(R) Core(TM) i3 CPU M 330  @ 2.13GHz
Memory:  4GB
OS:      Ubuntu 10.10 2.6.35-28-generic-pae i686

我的测试结果

escape延后处理是需要性能代价的。但是这样可以减少业务复杂性。

场景1:No escape

渲染10万次,最快的是doU, doT, nTenjin(基于tenjin的优化版本), jst_speed;最慢的是tenjin和jade doT已经达到百万次级别了,好神速啊! !!!新增@shaunlee 的中国第一速度模板引擎: jst, @shaunlee看见第一次测试结果后非常不满意,经过优化后,速度已经达到第一梯队了!

No escape, render 100000 times:

doT running...
use: 0.066 sec, rps: 1515151.5151515151
--------------------------------------------
doU running...
use: 0.064 sec, rps: 1562500
--------------------------------------------
nTenjin running...
use: 0.069 sec, rps: 1449275.3623188403
--------------------------------------------
jqtpl running...
use: 2.059 sec, rps: 48567.26566294317
--------------------------------------------
ejs running...
use: 1.514 sec, rps: 66050.19815059446
--------------------------------------------
haml running...
use: 9.532 sec, rps: 10490.97775912715
--------------------------------------------
jade running...
use: 10.592 sec, rps: 9441.087613293052
--------------------------------------------
jst running...
use: 2.089 sec, rps: 47869.79415988511
--------------------------------------------
jst_speed running...
use: 0.065 sec, rps: 1538461.5384615385
--------------------------------------------

场景2:All escape

性能马上变成浮云了。 速度高低排名: jst(果然是第一速度), nTenjin, jqtpl, ejs, doT, doU, haml, jade 对比场景1,可看到doT和doU的escape性能非常差。

All escape, render 100000 times:

doT running...
use: 3.921 sec, rps: 25503.698036215254
--------------------------------------------
doU running...
use: 3.926 sec, rps: 25471.217524197655
--------------------------------------------
nTenjin running...

从tenjin到nTenjin的几点性能优化方法

原文: https://github.com/QLeelulu/nTenjin/blob/master/README.md

模板引擎优化步骤

  1. 使用new Function 解析;
  2. 直接字符从相加 str += s;
  3. 变量不切换上下文,直接it指定
  4. 高性能的escape
