   Thanks @jpountz -- I had done a full system update (`pacman -Syyu`) on 
2025-05-01, and lots of packages were updated, including kernel:
   
   ```
   [2025-05-01T10:18:13-0400] [ALPM] upgraded linux (6.12.4.arch1-1 -> 
6.14.4.arch1-2)
   ```
   
   So maybe one of these other packages somehow caused the slowdown ... but 
first I'll try putting just Java 23 back and then we can see/iterate.
   
   I'm also not liking these unrelated hardware errors!!  But they are 
pre-existing for a long time now...
   
   ```

   Yay ECC RAM!
