Why and when to perform this task
In the default IBM HTTP Server for distributed platforms configuration, the maximum fast cache accelerator dynamic cache size is calculated as 1/8 of physical pin-able memory. On a machine with 384 megabytes of RAM, it allows a maximum of approximately 50 megabytes for the Fast Cache Accelerator dynamic cache. When this limit is reached, the cache accelerator deletes older entries to cache new entries.
Step for this task
AfpaEnable AfpaCache on AfpaLogFile "c:/Program Files/IBM HTTP Server/logs/afpalog" V-ECLF AfpaDynaCacheMax 10
These above settings limit the dynamic cache size to 10 megabytes. If you use these directives to increase cache size, do not make the cache so large that all the physical memory is consumed. Determine how much memory is available when all applications are running, by using the Windows Task Manager.
Assign no more than 50% of available physical memory to the dynamic cache. Specifying too large a cache not only decreases the performance of other applications, but also puts you at a risk for completely running out of memory.
The default configuration does not include the AfpaDynaCacheMax directive where the cache size is automatically calculated as 1/8 of physical memory.
