Lock files purpose is to lock dependencies of given package, at a current switch installation state, in order to share working dependencies. It's a simple opam file with more constrained...

Does it resolve the issue?

What is you usecase exactly? > By the way, is there any convention when it comes to name the switch export file? Not really, usually the extension `.export` i think.

This can come from the depext check. At each switch load, as for external file dependencies, depext checks that required system packages are still present. This check takes ~1s on...

It is indeed possible to compute availability only with subset of targeted packages, but a package availability depends on depexts, we still need to load it. A more optimised solution...

@vbmithr You can see what takes time with `--debug` timestamps (disabled with `--safe`). As it is 2.0.7, it is not a depext loading taking time, please open a new issue.

From the log, the repo cache takes 0.3s and the invariant to infer 0.3 more. Setting the invariant with `opam switch set-invariant` would reduce that time.

It is the same mechanism involved, indeed. My previous comment is more a hint, until this is fixed/improved/next release.
