Interactive performance will suffer greatly if the system pages a lot. Fortunately, memory is becoming relatively cheap. No Sun system, including personal diskless nodes, should be configured with less than 16 Mb of main memory; 20 Mb or more is recommended if you plan to do a lot of image processing. On servers, 32, 64, or even 128 Mb is not an unreasonable amount of memory to try to configure the system with.
