  (A) set maxphys  To improve basic disk performance  maxphys is the maximum size of physical I/O requests. If a driver sees a request larger than this size, the driver breaks the request into maxphys size chunks. File systems can and do impose their own limit. This value should be higher than all other settings (vol_maxio, vol_maxspecialio etc) such as in Filesystems/Volume Manager etc. maxphys is set in bytes.  Maximum number of page I/O requests that can be queued by the paging system. This number is divided by 4 to get the actual maximum used by the paging system. It is used to throttle the number of requests as well as to control process swapping. maxpgio is in I/O's.  C)Set FastScan  (Is Calculated by Multipliying 32678 for Physical Memory D)Set Handspreadpages(Is Calculated by Multipliying 32678 for Physical Memory  The Solaris environment uses a two-handed clock algorithm to look for pages that are candidates for reclaiming when memory is low.
