Hyper-threading Support on Intel Processors
From InterBase
Go Up to Server Configuration
InterBase can support hyper-threading on Intel processors that support logical processors using Intel hyperthreading technology. To enable this support in the InterBase server, you must make a setting in the InterBase configuration file, ibconfig. If you are running the InterBase server on a machine with hyper-threaded processors, edit the ENABLE_HYPERTHREADING parameter in the configuration file. By default, this parameter is set to zero. Set the value to 1 to allow the InterBase server to use hyperthreaded processors.
