I've got an issue in our application when I fire off a few dozen HTTPS requests curl_multi_perform is blocking for 15+ seconds.
I took this example and modified it to just make 30 HTTPS requests: https://curl.haxx.se/libcurl/c/multi-app.htm When I compile multi-app and link it to the libcurl 7.29.0 installed on RedHat at the system level (using just gcc multi-app.c -lcurl) I can reproduce this long pause of 15+ seconds. Next, if I download libcurl 7.42 or even the same version 7.29 and build that myself, and link against it, I'm able to get the requests to fire off in 1-2 seconds total. I've tried enabling/disabling AsyncDNS via c-ares as that was a difference I noticed between the system level library and the ones I compiled manually but it didn't have any effect. Currently I am stumped as to how to continue. Any ideas on how to debug this or what to check? Let me know if I can provide any further info. ------------------------------------------------------------------- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.haxx.se/mail/etiquette.html
