- Cheat Sheet on Curl Performance Metrics: how to benchmark server latency with curl
time_namelookup: how long DNS lookup took (translating domain name to IP address) time_connect: how long TCP handshake took (done by both HTTP and HTTPS) time_appconnect: how long SSL handshake took (only for HTTPS) time_redirect: how long the redirect took. It is 0 if there is no redirect. Need “-L” flag in curl to redirect. time_pretransfer: This is essentially an alias for either time_appconnect or time_connect (depending on HTTP or HTTPS). It is only useful as a delineator of when the specific request to the server has begun. time_starttransfer: This is when the server is ready to deliver bytes. Same as TTFB (Time To First Byte). It includes time_pretransfer, just subtract time_pretransfer from the time_starttransfer to get the amount of time spent in this phase time_total: The total time of the entire curl call. Calculate time_total - time_starttransfer to get the data transfer (a.k.a. download) time.

# iftop reports the bandwidth used by individual connections # it cannot report the process name/id involved in the particular socket connection. # The n option prevents iftop from resolving ip addresses to hostname, which causes additional network traffic of its own. sudo iftop -n sudo iptraf tcptrack
