From 5682e503255432fc2ebf0dbc4d9a0dd2055a1a2e Mon Sep 17 00:00:00 2001 From: Shigeki Ohtsu Date: Wed, 27 May 2015 10:33:38 +0900 Subject: [PATCH] deps: add -no_rand_screen to openssl s_client In openssl s_client on Windows, RAND_screen() is invoked to initialize random state but it takes several seconds in each connection. This added -no_rand_screen to openssl s_client on Windows to skip RAND_screen() and gets a better performance in the unit test of test-tls-server-verify. Do not enable this except to use in the unit test.
