Does layered view structure slow down validate lookml

[kendrickp]

We have structured our lookml to have a raw DB view file that is not to be touched. Then we extend these view files into other files where we create our measures. Could this structure slow down the validate lookml?

There is a short description of how the validator works here. But to answer your question, given that one of the factors in how long validation takes is the volume of code, then it is indeed possible that having base views and extending them could add to total validation time - but you can mitigate this by being careful about which files you include (include only necessary files where possible, avoid including everything) and - if needed - splitting your code into different projects when they get to a size that noticeably slows validation.
