各位大佬咨詢一下，我使用webman在本地測試有24w的 QPS,但是在局域網(wǎng)測試的話就瞬間降低了3.6倍,網(wǎng)卡是萬兆的網(wǎng)卡這問題會出現(xiàn)在什么地方?

本地127.0.0.1不走網(wǎng)卡

橘叔 2022-05-19

謝謝大佬指點(diǎn)，我有疑問，萬兆的網(wǎng)卡怎么會直接降低將近四倍的性能
842461193 2022-05-19

你走網(wǎng)卡就肯定有性能損耗啊，你ping下127.0.0.1和局域網(wǎng)ip看下延遲就知道了

壓力機(jī)也是萬兆網(wǎng)卡？

橘叔 2022-05-19

恩，兩臺都是萬兆網(wǎng)卡

直接在本機(jī)用 http://192.168.3.26/ 壓測下，如果還是差別這么大，就是走網(wǎng)卡導(dǎo)致的。如果出入不大，那可能是兩臺服務(wù)器間連接的路由器或者交換機(jī)問題，比如路由器或者交換機(jī)不是萬兆出口的。還有網(wǎng)線可能不是萬兆網(wǎng)線。

我本機(jī)壓測192.168.3.26更快...

那可以考慮壓力機(jī)自身是否有問題。還有路由器、交換機(jī)、網(wǎng)線這些是否支持萬兆帶寬這些問題。
