PC Performance for ProcessLogix Systems 9-13
Client/Station Memory Settings
Based on the Operating System and application usage, this system
should not be affected by paging operations as long as the memory is
at the specified amount of 128 MB. If adjustments are needed, you
should follow the default rules of the Operating System suggestion:
Example for a 128 MB System
Initial Size: 192 MB
(or default Operating System suggestion.)
Maximum Size: 384 MB
(or default Operating System suggestion.)
Servers with 128 MB of Physical RAM or Less.
Based on the Operating System and application usage, this system can
be severely affected by paging because the amount is less than
required. Smaller systems may be able to take this performance hit,
but medium to large systems will not be able to adequately perform.
Adjustments for this type of system are required for operation. The
settings suggested below should allow the system to run, but a
memory upgrade is highly suggested:
Initial Size: 300 MB
Maximum Size: 450 MB
Servers with 256 MB of Physical RAM or More.
Based on the Operating System and application usage, this system
should not be effected by paging as long as the memory specifications
are followed for the system size and usage. If adjustments are needed,
you should follow the default rules of the Operating System
suggestion:
Example for a 256 MB System
Initial Size: 1.5 times physical or default
Operating System suggestion. (Eg. 384 MB)
Maximum Size: 3 times physical or default
Operating System suggestion. (Eg. 768 MB)
