[erlang-questions] Slow response of post method of https request using httpc erlang module
Thu Aug 29 15:32:46 CEST 2013
We send thousands of httpc requests(post) in parallel to server. Which
internally does ssl communication for every request.
What do you mean by " configuring httpc to allow more parallel
connections"? How can we do it.
