It was a price performance measure. The actual throughput was quote, "The performance score of Solaris, measuring transactions per minute, was equally impressive: 6679.50tpmC throughput." This was Oracle on an IBM PC Server. Contrast this with the Compaq/Sybase/UnixWare benchmark in November. "The TPC-C result of 8,311.43 tpmC was based on a ProLiant 5000 configured with four 200 MHz Pentium Pro processors each with 512KB cache, 4-GB of memory, using the SCO's UnixWare operating system version 2.1.1, running Sybase's SQL Server 11.0.3 database application." I wonder which difference make the difference. Solaris which is supposedly very advanced with it's kernel threads and slab allocators, etc doesn't perform as well as UnixWare which I think has a simpler model. I think UnixWare has a very good AIO implementation, so reads and writes to raw partitions blaze. Regards, Mike Hancock
