For a small/medium site? Optimize images sizes/resolutions & keep the JS dependencies in check to only actually used code, or optimize to get the most important data rendered ASAP are much more important then adding a minifier script in the release pipeline (and I'm assuming gzipping the content is basically done for free everywhere nowadays). All of this especially in the spirit of TFA that encourages people to poke around JS code while browsing websites (as people did in the past with pure HTML)
