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.

Default: 32 or 128
