Lyris requires a minimum of 5 megabytes of RAM to operate. This amount of memory must be available after the operating system loads in order for Lyris to work.
In practical terms, this means approximately:
Windows NT 3.51 & NT 4.0 on Intel and DEC Alpha hardware: 48 megabytes RAM.
Windows 95: 32 megabytes RAM.
OS/2 version 2.0, Warp and Merlin: 24
megabytes RAM
Macintosh System 7: 24 megabytes RAM.
Unix: 48 to 64 megabytes total RAM.
Note that if you plan to have a very busy Lyris Server, more memory is better.
If you have at least 1 megabyte of physical memory available, then it is likely that you are using your hard disk swap-file for memory, and your system will perform quite slowly.
If, when you are running Lyris, you have a great deal of hard disk activity, it is likely that you are low on memory. Lyris has its own disk-caching mechanism, and is very efficient in its use of the hard drive. Under normal circumstances, you should not hear the disk thrashing about. This, heavy disk activity is a sign that your system is low on memory.
