| == Page Clearing alternatives bandwidth tests == | |
| == == | |
| == Here we will do bandwidth test of all the page clearing alternatives. == | |
| == First feature detection is done i.e., if a instruction is micro code == | |
| == optimized, and that feature is present on system being tested, then only == | |
| == results are displayed, otherwise user is informed about feature not == | |
| == supported and tesing moves on to next alternative. == | |
| == == | |
| == Note 1: Result is devided into two parts: First table contains results == | |
| == when cache is hot & second table contains result for cold cache == | |
| == Note 2: Speed is specified in Mega bytes per seconds == | |
| == Note 3: For all the page clearing alternatives, bandwidth is measured at == | |
| == buffer sizes : 4k, 8k, 16k, 32k, 512k, 1MB, 2MB, 32MB and 64MB. == | |
| == Note 4: If sample standard deviation exceeds 0.1%, it is shown in == | |
| == brackets == | |
