sar is nice when you can get it.

It  certainly is  more  difficult  with the  default  columns that  Task
Manager/Processes  shows.  You  do  know, however,  that  you  can  add
additional  columns  to  the  Task Manager/Processes  window?  It  will
actually show you some cool stats like disk I/O (write/read), memory and
paging  deltas, and  a couple  dozen  other things.  That still  doesn't
eliminate  the svhost  problem you  mention, but  at least  for uniquely
named processes it helps considerably.

Click View->Select Columns and choose the ones that interest you.
