在 LAN 裡把 TCP timestamps 關閉擠出頻寬

由於 TCP timestamps 會使得封包多 12 bytes,關掉後可以在 LAN 裡面擠出頻寬,是個小孩子不要亂學的方法:「Save Some Bandwidth By Turning Off TCP Timestamps」。

文章裡是在 10Gbps 網路上測試,看測出來的圖片也只是一點點 (不到 1%),但仍然是有提昇:

Results show that it's reasonable to turn off timestamps on 10GE interfaces, but keep in mind that it should be performed only in low latency networks.

沒必要就不要亂動 :o
