Enabling this option increases code size (around 20%) and
|
|
performance. The increase in performance and size depends on the
|
|
target CPU. EC and AES seem to benefit the most, with EC speed
|
|
increased by 20%-50% (mipsel & x86).
|
|
AES-GCM is supposed to be 3x faster on x86. YMMV.

TLS 1.3 is the newest version of the TLS specification.

It aims:

|
* to increase the overall security of the protocol,

removing outdated algorithms, and encrypting more of the

protocol;
|

* to increase performance by reducing the number of round-trips
