I've been thinking whenever that kind of optimization does apply also to Tor or not?
Tor uses TLS only for node-to-node transport encryption. Any improvements to Tor's TLS behaviour would therefore only result in occasionally faster circuit building times. This may be nice to have, but because Tor builds circuits preemptively and therefore can switch circuits quickly, I doubt that this is an actual bottleneck in the system.
