I'm running a SAAS service running via NGINX and have been running tcpdump to look at the incoming packets for HTTP queries. Many of the HTTP queries are bigger than the MTU of 1,500 bytes and therefore arrive as 2, 3, or 4 packets. I noticed that for some customers there are significant delays between packets. The average size of these delays acts as a kind of fingerprint for each customers. Theby SimonHF - Nginx Mailing List - English
