joeyta備忘記: Eclipse TPTP 備忘記

Eclipse Test & Performance Tools Platform (TPTP) 為 Eclipse 基金會的開源項目.
這個項目的主要目的為在 Eclipse IDE 平台集成性能測試, 調節, 監察等功能.
這次備忘記是學習如何增加讀取 xml 的執行性能.

開始備忘記:
[1] 安裝 jdk 5
[2] 安裝 Eclipse 及 Eclipse TPTP
[3] 性能調節的案例實踐

[1] 安裝 jdk 5：
下載 jdk-1_5_0_07-nb-5_0-win-ml.exe
http://java.sun.com/j2se/1.5.0/download-netbeans.html
安裝至 D:\jdk1.5.0_07
新增環境變數 JAVA_HOME=D:\jdk1.5.0_07
D:\jdk1.5.0_07\bin 加入至 PATH 中
D:\jdk1.5.0_07\lib\dt.jar 及 D:\jdk1.5.0_07\lib\tools.jar 加入至 CLASSPATH 中
執行 D:\>java -version
輸出 java version "1.5.0_07" 即安裝成功.

[2] 安裝 Eclipse 及 Eclipse TPTP:
安裝 Eclipse:
下載 eclipse-SDK-3.2.1-win32.zip
http://www.eclipse.org/downloads/
http://ftp.jaist.ac.jp/pub/eclipse/eclipse/downloads/drops/R-3.2.1-200609210945/eclipse-SDK-3.2.1-win32.zip
解壓縮至 c:\eclipse_tptp

安裝 Eclipse TPTP:
點擊 c:\eclipse_tptp\eclipse.exe 執行 Eclipse
選擇 Help -> Software Updates -> Find and Install -> Search for new features to install
按 Next 後點選 Callisto Discovery Site 後按 Finish
然後選擇最接近的下載點安裝, 然後隨 C and C++ Developement 外, 全部安裝.
如下圖所示

這裡下載安裝使用超過20分鐘. 最好選擇較接近的下載點.

[3] 性能調節的案例實踐:
這裡主要是參考以下網站內容:
http://www.eclipse.org/articles/Article-TPTP-Profiling-Tool/tptpProfilingArticle.html
project 下載點為:
http://www.eclipse.org/articles/Article-TPTP-Profiling-Tool/productCatalogSample.zip
解壓縮至 C:\eclipse_tptp\workspace\productsample

下載測試檔案 xmlProductFiles.zip
http://www.eclipse.org/articles/Article-TPTP-Profiling-Tool/xmlProductFiles.zip
解壓縮至 c:\products

裡面包含 24 個 xml 檔案, 內容像下面這些:

<?xml version="1.0" encoding="UTF-8"?>
<content>
<product name="Apple" price="1.99" type="Golden" production="Canada"/>
</content>

<?xml version="1.0" encoding="UTF-8"?>
<content>
<product name="Corn" price="0.45" production="Chile">
</product>
</content>

<?xml version="1.0" encoding="UTF-8"?>
<content>
<product name="Potato" price="0.35" production="Ontario">
</product>
</content>

建立 java project 名為 productsample
File -> New -> Project -> Java Project -> Next
Project name 為 productsample
然後按 Finish
productsample project 裡只有 ProductCatalog.java 及 Product.java 兩個 class
如下圖所示:

然後右鍵點選 Product -> Profile As -> Java Application
選擇 Arguments [Tab]
program arguments: 輸入 c:\products
如下圖所示

切換至 Monitor [Tab]
選擇 Java Profiling -> Execution Time Analysis
如下圖所示

點選 Execution Time Analysis 後按 Edit Options
選擇 Collect boundary classes excluded by the filter set
Boundary class depth 輸入 3 [這是呼叫 method 的深度]
然後按 Finish
如下圖所示
