A team of researchers at the Database Research Group at Waterloo University led by Xiufeng Liu, have published a paper, Benchmarking Smart Meter Analytics. They built a simulated smart meter database and used open source software and kdb+ to perform a set of standard analytics.
The results are quite interesting. Check the paper out here, and note, the pseudonym “System C” refers to kdb+.
You can find Xiufeng Liu’s benchmarking code on GitHub here.
