關鍵字：TCP netio
我們應該都比較想知道CC3200的速度有快，特地花了一晚上的時間寫這個測試。
測試環境：CC3200作爲STA連接家裏的網絡，自己的電腦也連上家裏的網絡，使用的測試方法是netio，我自己模仿了netio編寫了代碼。我的電腦也是用無線連網絡的，所以速度可能會慢點，因爲我的電腦不能發現CC3200的ap，所以想直接連好像沒辦法，如果你能直接連，並測試了，請發測試圖片給我，謝謝。因爲wifi可能有涉及到某些設置（窗體啊，或者是其他的參數，我也不太懂），因此測試僅供參考，如果你對改進wifi速度有啥建議，請教我下。謝謝。

測試結果：
左邊的是電腦的，右邊的是cc3200打印的，因爲我在cc3200的定時器是秒爲單位的，不能精確到毫秒，圖簡單，因此兩邊的速度可能有些差異。
參考代碼：沒有實現udp的測試
