Option to get faster machines to build with?


We are building some C++ code in docker containers using CircleCI 1.0, however the builds are taking an extremely long time. They seem to run fine when they are actually building, but spend most of their time hanging and doing nothing, suggesting there is some heavy CPU throttling going on. Is there an option to upgrade to a plan with faster build machines? All I see is additional containers for parallelism and concurrency which is useful but doesn’t help speed up individual builds.
