• EdDSA is faster as and ECDSA are not only more secure, but also faster than RSA
  • RSA causes slower connection as it has bigger overhead

• long term future plans of SSH community are to get rid of RSA.replace DSA and RSA with at least ECDSA or best with EdDSA which is being widely adopted for several years
• long term TDS plans are to get rid suppress usage of DSA/RSA keys supportand motivate end users to use EdDSA keys
