Is this true? Yes, this is true. From http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/configtuning-init= ial.html: "On larger systems with multiple SCSI disks (or multiple IDE disks operating on different controllers), it is recommend that a swap is configured on each drive (up to four drives). The swap partitions should be approximately the same size. The kernel can handle arbitrary sizes but internal data structures scale to 4 times the largest swap partition. Keeping the swap partitions near the same size will allow the kernel to optimally stripe swap space across disks" Hopefully your first question will be answered by somebody else. --=20 Dmitry "We live less by imagination than despite it" - Rockwell Kent, "N by E"
