As much as is reasonable to purchase. Postgres would probably appreciate the memory more than ZFS. You can run ZFS on memory-limited machines (I've gone as far down as 256MB), but the critical part is running a 64-bit kernel. ZFS does a lot of kernel malloc/free operations, and address space fragmentation on a 32-bit system will eventually cause a panic when ZFS can't malloc a contiguous 128k chunk. -- Dan Nelson dnel...@allantgroup.com _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
