HN discussionThere are commercial products that you can leave running all the time to generate data from your packets on the fly, such as ExtraHop ( http://extrahop.com ). There are also continuous PCAP tools, but they need massive amounts of storage and in larger environments the lookback you get is limited.

HN discussionI suppose I should say something. The thing to turn off is delayed ACKs. See "TCP_QUICKACK". Delayed ACKs were a feature which is only useful for things like Telnet, where the payload in each packet is one character when the user is typing. The fixed timer for delayed ACKs is for keyboard typing speeds, and for networks so slow that human typing could congest them. There's a reasonably good explanation here.[1] As o…
