在我們的性能測試中，我們遇到了很高的CPU使用率（100％），線程轉儲表明線程正在執行恢復視圖或呈現JSF生命週期的響應階段的大部分時間或者在訪問包含xhtml頁面的jar文件時被阻止。JSF生命週期階段執行期間CPU使用率高
一個可運行線程的線程轉儲的是

我們使用的GlassFish 3.1.1作爲我們的應用程序。我想獲得有關如何進一步調查的建議。這是一個正常的行爲？ glassfish是否提供瞭解決阻塞線程的替代方案，如資源緩存機制等？
在此先感謝
看起來像是解壓縮jar文件... –
xhtml頁面在jar文件中。訪問jar文件時看到很多線程被阻塞。任何替代方案？任何玻璃魚設置可能會緩存這些？ –
將web.xml中的jsf項目階段設置爲開發？這可能會禁用任何緩存並導致重複訪問jar文件。 –
