6.1. Memory requirements

The windowing systems used in these workstations tend to be very memory intensive; the typical screen with ten or so windows uses a lot of memory. With the introduction of the virtual files system in SunOS 4.0, the memory requirements of SunOS and hence Solaris have increased ever further. 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 32 Mb of main memory; 48 Mb or more is recommended if you plan to do a lot of image processing. On servers, 64, 128 or even 256 Mb is not an unreasonable amount of memory to try to configure on the system.
