Is this the expected behavior when pause/resume is used? Yes, it is expected. There's no logic that deducts the paused time, so you get the transfer size divided by the total time used, including all the paused time. -- / daniel.haxx.se | Commercial curl support up to 24x7 is available! | Private help, bug fixes, support, ports, new features | https://curl.se/support.html --- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.se/mail/etiquette.html
Question on CURLINFO_SPEED_DOWN/UPLOAD when paused/resumed
Hi all, I just wanted to see if I could clarify something (that I think is correct but just thought I'd ask), I'm using curl multi transfers and pausing and unpausing single curl transfers as needed. I am also looking at CURLINFO_SPEED_UPLOAD and CURLINFO_SPEED_DOWNLOAD when the single transfers are done; and I am pretty sure that this is the case but just wanted to double check: When pausing and resuming I was noticing that CURLINFO_SPEED_UPLOAD and CURLINFO_SPEED_DOWNLOAD and its counters/timers don't seem to reset (which may just be how it is) and from looking at the progress.c code I think this is what is happening. So if a long pause happens, then the speed counters/timers may not actually take into account the fact that the transfer was paused for quite some time which then would produce a not exactly valid upload or download speed. Is this the expected behavior when pause/resume is used? Much appreciated, -josh --- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.se/mail/etiquette.html
