I would like to know what is being compared to what when claims of doubling the performance are made. For example if the cloud has a total of 400 cpus, 100 TB of mirrored raid 5, 200 ports of 10GigE, and 1600 GB ram,...etc...etc is the performance benchmark compared to a similarly equipped large scale SMP machine with same type and speed of cpus and ram, same type and size of storage, same OS and same app, and same backplane as the machines in the cloud? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
