I’m currently writing a new standard for TLS which will allow the client to cache big portions of static data exchanged during TLS handshake negotiations and allow the server to omit resending this data on consecutive handshakes, such as in consecutive re-negotiations.

My slides for the TLS meeting today at the Hiroshima IETF, showing the basic approach. is available here: Cached Info (PDF).

The standard is ready for work group last call and will hopefully be published as an IETF standards track document in the beginning of next year.
