You can and should safely reuse a SSL_CTX object, so that you don't need to
reinitialize things like the certificate stuff.
An SSL object can also be reused, you should however make sure to call
SSL_clear() on it before reuse.
I cannot give you numbers on the performance impact of SSL_new() or
SSL_CTX_new(), respectively. Both functions do however call functions
of the malloc() class quite often, so that memory fragmentation might
occur. For this reason alone, I would already recommend you to reuse SSL
and SSL_CTX objects.
Best regards,
