Both VeriTest (formerly ZDlabs) on Microsoft's behalf and IBM have recently issued reports on running Ziff Davis Media's NetBench performance benchmark on mainframe Linux. The results are not directly comparable because IBM used a dedicated 16-CPU z900, while VeriTest was restricted to a two-CPU partition on a z900.

"Overall, however, it appears that Microsoft reports better mainframe performance than IBM does. The IBM z900 two-processor LPAR achieved 14 percent less performance at nearly 20 times the cost when compared with an ordinary server with two 900-MHz Intel Xeon processors running Windows Server 2003.

"These results might seem surprising enough to those unfamiliar with mainframe Linux, but the truly astonishing thing here is Microsoft's apparent reticence in presenting results that dramatically favor the Windows platform.
