Staging assets:precompile is incredibly slow on 4.0.0-pre.3 #1785
Description
When upgrading from v3.5.5 to v4.0.0.pre.3 to test the pre-release, I noticed that my staging deploy went from taking approx 10-15 minutes to over 2 hours, stuck on the assets:precompile step after Sprockets has completed.
Production deploy is untested.
Would be happy to share any necessary files. Here's my .babelrc if it helps:
