Casper;

Does this mean it would be a good practice to say increase the amount of memory and/or swap space we usually recommend if the customer intends to use ZFS very heavily?


ZFS doesn't necessarily use more memory (physical or virtual) than UFS it needs more VM *address space* (not the same as more VM) hence the 64 bit processor.

   offtopic query :
   How can ZFS require more VM address space but not more VM ?

thanks.
