No, tuning doesn't take long. It just seems easier and more stable not to run tuning on the builders at all. Note that tuning might be sensitive to cpu load, so it's preferably to run on an otherwise idle box, which builders may not always be.

If a tuned build is needed, one can use `-o native_build` which will enable tuning.
