網站後端快取架構之設計與其效能驗證之研究

由於網路的普及，至今網頁已越來越普遍，在這種情況下Web伺服器效能的重要性相對而言就重要多了，為了提升網頁效能、縮短回應時間以及再用性，因此有了許多相對應的快取技術的產生。在本研究中，我們認為透過伺服器後端快取技術應能大大提升網站效能，因此設計一個伺服器快取架構並且利用Python和Java實作之。另外也設計了一個實驗來驗證之我們利用JavaScript撰寫在後端持續發送Web請求，再利用JSON做一個簡單的自動化設定，最後也確實驗證了我們的推論。最後分析伺服器在相同條件下在時間內處理大量請求時所需花費的時間以及檔案快取的差異。

Recently due to the popularity of the Internet, web pages have been more and more popular. In this case, the importance of web server performance is increased. In order to improve web page performance, shorten response time, and reusability, there are many corresponding cache technologies proposed. In this study, we believe that server back-end caching technology should greatly improve website performance, so we designed a server-side cache architecture and implemented it using Python and Java. In addition, we also designed an experiment to verify that we use JavaScript to write and continue to send Web requests on the back end, and then use JSON to make a simple automated setting, and finally verified our inference. Finally, analyze the time it takes for the server to process a large number of requests within the same time and the difference in file cache.
