Description:

   just running # time ls /var*; after booting bsd.rd
   takes like 14 seconds, according to my phone clock

   don't know if it happened before because i'm just starting to
   try vmm

   i ran out of patience when trying to install OpenBSD
   because it takes ages...

   how to diagnose further?

   thanks
