If you are finding your builds are taking a long time, perhaps it is the version of Unity you are using. After updating to the latest 2021.3.3f1 LTS my build times jumped 6x over the previous LTS 2020.3.26f1 version. I tried a number of other non LTS and even Beta versions of Unity and none come close to 2020.3.26f1 in terms of build times no matter the fiddling. Here are two identical small builds with the faster being 2020.3.26f1 and the slower latest LTS 2021.3.3f1. This is a big deal as we all know optimizing for Quest requires a lot of test builds and that longer build time can really add up especially when I build my entire project and have to wait 45 mins versus 15 mins. Love to hear if you have a different experience.
