Yes, just to confirm: Starting without snapshot, especially in Debug mode, has become much slower, because more work is being done there (mostly compilation of builtins and bytecode handlers).
This is working as intended. I.e. it's not considered a bug/problem, will not be improved over time, in fact it could get even slower and we wouldn't care. The officially supported/recommended thing to do is to build with snapshot.
