  • Are you talking about the execution time of the server that runs the CURL code or the other server that's being called by CURL? If it is the other server, I would say that it is not possible to get an execution time - what you can calculate is a response time (which includes network latency) Commented Aug 11, 2011 at 12:26
  • am talking about the server that host the pasge am requestion: by execution time I mean the time that the server puts calculation the result that am requestion! Commented Aug 11, 2011 at 14:36
  • The answer provided by @DaveRandom would give you the time it tool your server to get the response. Try comparing that to the total_time reported back from CURL. Also info about difference in STARTTRANSFER_TIME and PRETRANSFER_TIME Commented Aug 12, 2011 at 0:22

Regarding STARTTRANSFER_TIME and PRETRANSFER_TIME.

Starttransfer_time

Pass a pointer to a double to receive the time, in seconds, it took from the start until the first byte is just about to be transferred. This includes CURLINFO_PRETRANSFER_TIME and also the time the server needs to calculate the result

Pretransfer_time

Pass a pointer to a double to receive the time, in seconds, it took from the start until the file transfer is just about to begin. This includes all pre-transfer commands and negotiations that are specific to the particular protocol(s) involved
