I am going to use for a high performance load testing.As per you information curl_multi_perform() API will return once all easy handle transfer the data.
Yes. It returns when it has sent the data it can send *right now*.
So It will block the operation to complete the transfer for all easy handle.
No it won't. Did you really read https://curl.haxx.se/libcurl/c/libcurl-multi.html and come to that conclusion?
You could also consider reading the "Drive with multi" section in my (pending) curl book: http://ec.haxx.se/libcurl-drive-multi.html
In my project we need, if first time the data transfer is not complete then we will call next time based on the notification of data availability. My application will create huge no of child process and each child process will invoke curl_multi_perform().
If you intend to go above a few hundred parallel connections I advice you to bump up to the multi_socket API, which is event-based. That allows you to perform well even when you scale up to ludicrous amounts of connections.
