He estado comparando mi rendimiento de TLS y noté que durante la fase de "intercambio de claves de escritura del cliente", hay una sobrecarga significativa en comparación con todas las demás acciones. Me pregunto si hay algo que pueda hacer para acelerar esto.
40348.989720O ssl_info_callback SSL_connect SSLv3 read server certificate A
140348.989934O ssl_info_callback SSL_connect SSLv3 read server key exchange A
140348.989954O ssl_info_callback SSL_connect SSLv3 read server certificate request A
140348.989968O ssl_info_callback SSL_connect SSLv3 read server done A
140348.990606O ssl_info_callback SSL_connect SSLv3 write client certificate A
140349.29131O ssl_info_callback SSL_connect SSLv3 write client key exchange A
140349.35914O ssl_info_callback SSL_connect SSLv3 write certificate verify A
140349.36013O ssl_info_callback SSL_connect SSLv3 write change cipher spec A
140349.36062O ssl_info_callback SSL_connect SSLv3 write finished A
140349.36077O ssl_info_callback SSL_connect SSLv3 flush data
140349.36094O ssl_info_callback SSL_connect error in SSLv3 read server session ticket A
En base a esto, parece que el intercambio de claves del cliente toma ~ 300 ms
