Meta Group believes the new 1Mb Level 2 cache for Intel Corp’s Pentium Pro chips will increase the performance lead of Unix servers over Windows NT. It says NT scalability on servers using the chip will likely improve only about 10%, due to constraints on both NT and SQL Server. However it expects a 30% improvement from Intel-based Unix systems, especially memory-hungry database applications. Meta says NT users will have to wait until next year, when the 300MHz Intel processor is available and Microsoft further enhances NT and SQL Server scalability.
