CACHE_LINE<size>
To maximize the performance of the FairCom Server under multi-CPU systems, ensure the cache-line setting matches the setting for your equipment. A cache-line is the smallest amount of memory a processor will retrieve and store in its highest speed cache. Using an appropriate CACHE_LINE setting helps reduce false sharing in CPU caches. Typical cache-line sizes are 32, 64, or 128 bytes.
It is common for 32-bit CPUs to use a 32-byte cache line size, and for 64-bit CPUs to use a 64-byte or larger cache line size, thus the default CACHE_LINE setting is 32 for 32-bit systems and 128 for 64-bit systems.
Supported CACHE_LINE values are: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, and 1024. If an invalid CACHE_LINE value is specified, the server logs a warning message to CTSTATUS.FCS and uses the default value.
Default: 32 or 128
