The problem is not so much processor physical memory but it's processor virtual memory; and virtual memory is limited by the amount above the address space on a 32 bit kernel. A 64 bit system with 512MB of memory does much better than a 32 bit system in the same situation. Lowering kernelbase (eeprom kernelbase=0x.....) will help some. (The default kernel base gives less than 1GB of virtual space) Casper _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
