Wow, I just posted this: [Precompilation much slower in 1.11, 1.12 than in LTS (1.10)](https://discourse.julialang.org/t/precompilation-much-slower-in-1-11-1-12-than-in-lts-1-10/135203) and then was pointed to this thread.

Indeed I have the exact same frustration as the original poster, both with precompile times and runtimes. You can look at my Github actions [here](https://github.com/bmad-sim/SciBmad.jl/actions) and see that, for every single release, 1.11 and 1.12 are much longer to precompile than 1.10. I have been only using LTS, and also point my users to install LTS specifically in my installation instructions. In my view, the _default_ Julia (e.g. when you install `juliaup`) should be LTS. Nonetheless, I have concerns that in the future when LTS is upgraded to a version above 1.10, 1.10 won’t be supported anymore…

We should change the title of this thread, because it is not just a Pluto.jl problem. This is across the ecosystem.
