<div dir="ltr"><div>Our Application (which uses existing Erlang OTP R15B01 modules) sends https request to external authentication server..and it gets reply and seems work fine under normal cases</div><div><br></div><div>
But under heavy loads some requests are failing since they are consuming more time to do ssl handshake</div><div><br></div><div>and i have observed the following things during ssl handshake</div><div><br></div><div>client is taking(our application ) nearly 80 sec to send the certificate after server hello is done with server certificate</div>
<div><br></div><div>since our server expects to complete the request- response in 30 sec otherwise it drops the connection hence results to connection failures and effects the performance of application severely</div><div>
<br></div><div>and finally i would like to know</div><div>- Is our application failing to invoke the client certificate quickly .? i mean does httpc module do the file/IO related operations to invoke the certificates which results to slow response under heavy loads..?</div>
