Should I be worried that my "Fast" memory is so low? It's got 256M DRAM, so I can't add any more because it is an RSP4. Is there are way to increase the Total? Or do I even care? 7507>sh mem Head Total(b) Used(b) Free(b) Lowest(b) Largest(b) Processor 42E00D00 220197632 128598280 91599352 89187504 66349960 Fast 42DE0D00 131088 126864 4224 4224 4184
