Tuning

Set the maximum heap size in the Admin Console in the Maximum Heap Space Size field on the configuration's Performance tab ⇒ Cache tab, under File Cache. In the command-line interface, use wadm set-file-cache-prop and change the max-heap-space property. The default value is 10485760 bytes. The range of values is 0-9223372036854775807. In a 32–bit Web Server, since processes have four GBs of address space for the file cache, the value should be well under four GB.
