As a workaround, you can set CURLOPT_CAINFO to point to a single certificate,
(possibly just a dummy certificate) a
Very appreciate for your help.

Sure, but not more than necessary. Doing many things at once do consume CPU!
If you want to avoid doing many TLS handshakes at once, you should consider

2. Does we have any plan to re-use SSL "context"?

For every call to curl_multi_socket_action(), libcurl will also take care of
other transfers that have a timer that has expired. None, one or many
transfers.

Hi Daniel,
I find some something, let me show you.
My application using epoll listen fd.
if(fd.events & EPOLLOUT) {
curl_multi_socket_action(multi, fd, CURL_CSELECT_OUT, &still_running);
}
I found two issues:

Thanks,I modified my application, but I still have HTTPS performance issue.
I send 40 https request at the same time. They all create new connection
and connect server.
I found CPU burst to 56%, then down, this high CPU time duration about
500ms .
I found https_connecting, maybe in handshake cause

Thanks for your response，i will retry this.
I have another question，for high performance，can i firstly create many easy

Does this make sense？if make sense，which API can do this for multi

thanks！

By the way I use hiperfifo.c to send HTTPS 40 requests at the same time in
