1 An overview of the six time values available from curl_easy_getinfo() 2 3 curl_easy_perform() 4 | 5 |--NT 6 |--|--CT 7 |--|--|--PT 8 |--|--|--|--ST 9 |--|--|--TT 10 |--|--|--|--|--RT 11 12 NT = CURLINFO_NAMELOOKUP_TIME. The time it took from the start until the name 13 resolving was completed. 14 CT = CURLINFO_CONNECT_TIME. The time it took from the start until the connect 15 to the remote host (or proxy) was completed. 16 PT = CURLINFO_PRETRANSFER_TIME. The time it took from the start until the file 17 transfer is just about to begin. This includes all pre-transfer commands 18 and negotiations that are specific to the particular protocol(s) 19 involved. 20 ST = CURLINFO_STARTTRANSFER_TIME. The time it took from the start until the 21 first byte is just about to be transferred. 22 TT = CURLINFO_TOTAL_TIME. Time of the previous transfer. This time does not 23 include the connect time (CT), so if you want the complete operation 24 time, you should add that. 25 RT = CURLINFO_REDIRECT_TIME. The time it took for all redirection steps 26 include name lookup, connect, pretransfer and transfer before final 27 transaction was started. So, this is zero if no redirection took place. 28
