Meaning what exactly: block storage like iSCSI for example?  Prometheus 
does not work well with NFS storage.

I am curious why ps and top slow inside the container? What they need?

In that case, it's clearly not a prometheus problem, it's something to do 
with your container or your k8s environment.  Try using strace to see the 
system calls, e.g.

strace -s 128 -f ps ....etc...  2>strace.out

then go through the calls in strace.out.  Adding "-ttt" can give you better 
timestamps.

Some possibilities: a problem with DNS; a problem with uid/gid resolution 
in nsswitch (especially if you're using something like an LDAP backend); a 
problem with one of your filesystems.
