web頁(yè)面與javawebsocket接口的

壓力測(cè)試

對(duì)于網(wǎng)站開(kāi)發(fā)，壓力測(cè)試是少不了的。壓力測(cè)試可以對(duì)網(wǎng)絡(luò)，服務(wù)器,

系統(tǒng)架構(gòu)的優(yōu)化程度進(jìn)行檢驗(yàn)。以便提前知道網(wǎng)站的負(fù)載能力，并未

優(yōu)化提供依據(jù)飛

對(duì)于網(wǎng)站的壓力測(cè)試，基本離不開(kāi)下面兩點(diǎn)的測(cè)試：W一b頁(yè)面訪問(wèn)的

壓力測(cè)試和java接口的壓力測(cè)試（我們接口是通過(guò)websocket實(shí)

現(xiàn)）。

web頁(yè)面訪問(wèn)壓力測(cè)試工具可以使用apache自帶的ab命令進(jìn)行檢

測(cè)；javawebsocket接口的壓力測(cè)試可以使用

Jmeter+websocket插件進(jìn)行檢測(cè)。
