Si prefieres hablamos en español.

we're currently working on a 8-processor sgi server with irix by now each
backend run in one processor there is no load balance
the amount of memory u will need is as I know (table size+indexes size) they are
in your base directory, if u can afford it then u will be working on memory
but fsync and walfiles
hope it help
