Benchmarks across versions

[dpo]

It would be great to maintain benchmarks to compare pull requests to develop, and to measure the improvements brought by a new revision.

BenchmarkTools.jl seems useful to benchmark solver building blocks.

I think we need a different tool to compare the performance of solvers across versions and across branches, e.g., using aggregate measures, performance profiles, etc.

This would be very interesting. Perhaps it can be done with JLD, after the tests? Maybe post in the site automatically. It might increase the travis time to the max, though.
