- ACIUS does give more info about that in the 4D Customizer dox. 4D is
- capable of using a very large partition of your RAM. It can use is for
- ..well... caching. 4D will cache data and code/layouts, which can be
- very, very useful fer instance when you have a nice little 7 page layout,
- and you're working from a structure file copy that's on a file server you
- are connected to by LocalTalk. 4D, with enough RAM, will hold that layout
- in memory until it's close, rather thatn having to load pages across the
- network as you flip from one to the other. Given the small size of the
- standard lowend mac monitor, I would expect something like this to be a
- not-too-uncommon situation (multi-page layouts, that is). After 3 years
- of both development and end-use of 4D databases, we have finally gotten
- out asministration to agree that 4Mb is a minimum RAM configuration for any
- new machine. We have not been able to get them to standardise on an
- '030 machine, however, so we still are buying lowend machines for dbase
- work, and have the small monitor/slow CPU problem. We are also encountering
- great resistance to ethernet migration... They LIKE it slow and painful.
- Acius's Customiser has been a big help, because we have been able to allow
- 4D to make the best use of what memory is available. 4D Customiser allows
- us to configure each databases memory useage for any of several different
- end-user possibilities (2/4/8 Mb RAM and various partitions thereof), so
- we can help 4D best use waht cache it has, based on the dbase's needs.
