Enable fast response cache accelerator. Enable the
fast cache accelerator by updating the following directives in the IBM HTTP
Server httpd.conf file:AfpaEnable
AfpaCache on
AfpaLogFile "c:/Program Files/IBM HTTP Server/logs/afpalog" V-ECLF
AfpaDynaCacheMax 10
These 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 of 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 one eighth of physical memory.
