測試
測試開始后，軟件會自動進行各項測試，並為其評分，測試完成后，將會輸出一個測試報表結果，以我的 Dell R410，配置為 E5507 16G內存，146G SAS Raid 0為例，結果如下：

為了進行對比，我同時也在我的開發機上運行了一個虛擬機進行測試，虛擬機設置了單核 CPU，2G 內存，測試結果如下：

由於虛擬機僅配置了單核 CPU，因此這里只有 1 parallel 單線程測試，並沒有上面服務器中的多線程測試。我們可以從兩份結果對比得出，由於不同世代的 CPU 技術差異，這里的 I5-4570 的單核表現與 XEON-E5507相比幾乎是性能翻倍。
評估
以上的測試給出的分數，我們可以作為評估的依據，但實際決策中，還需要考慮其他的情況。如服務器的安放、穩定性以及一起其他的功能，比如 Dell 的服務器支持 iDrac 遠程控制，可以通過網絡控制服務器開關、重啟以及監控設備運行情況等。如果單從運算性能看，可能會組裝一台 i5 的電腦性能更好，但如遇停電、或者死機的情況，沒有遠程控制維護服務器，那么就需要考慮其他的處理方案。
