My primary concern is with people (and I'm not claiming that you are one of them) publishing such experiments without huge "This should not be used in production!!!" warnings and some poor fool deploys it and gets pwned 3 months later. TLS does have some overhead because of its flexibility, yes. But it's still incredibly fast and should not be a bottleneck in most scenarios. Given that it has been battle-tested with very little flaws found (most bugs are implementation bugs, not protocol bugs), it is and will be for the foreseeable future the #1 option for anyone looking for a encrypt-data-while-in-transit solution.
