網站速度最佳化模組HttpCompressionModule

為了最佳化網站的訪問速度，準備採用HttpCompressionModule 6對傳輸資料進行壓縮，下載了HttpCompressionModule 6 , 並按照樣本程式中的web.config配置了網站的web.config。

   Here's an example on how to change the algorithm or compression level
   
      <compressionModule preferredAlgorithm="deflate|gzip" compressionLevel="high|normal|low"/>
   
   so, to use deflate by default, and high compression, you would use the following line
   -->
    <httpCompress preferredAlgorithm="gzip" compressionLevel="high">

使用效果：
使用HttpCompressionModule內建的Fetch工具進行測試，測試結果如下：

測試結果說明:
第一行資料是未使用HttpCompressionModule的測試結果。
第二行資料是使用deflate壓縮演算法進行壓縮後的測試結果。
第二列資料是Web伺服器傳遞到瀏覽器的檔案大小。很明顯，壓縮後傳輸資料大大減少，有效地節約了頻寬。
TTFB—首位元組平均回應時間（Gets the number of milliseconds that have passed before the first byte of the response was received.）
TTLB—末位元組平均回應時間（Gets the number of milliseconds that passed before the last byte of the response was received. ）
Transit—傳輸資料到瀏覽器的時間。
從測試結果可以看出, 採用HttpCompressionModule後訪問速度有明顯改善。
