使用sysctlhw . pagesize能获得硬件页面大小。
You can also use the ps -Z option to get the pagesize explicitly being used by different tools, as here in Listing 8.
You can see that the pagesize is set to 32k instead of the default 4k, which improves the performance in the event insertion process, resulting in a memory assignment of 2500*32k + 625*32k = 100 MB.
The pagesize is available by the system call getpagesize.
When you create a DB2 database on UNIX platforms, a default Buffer pool called IBMDEFAULTBP is created that is 1000 pages with a 4k pagesize.
Buffer pool must have same pagesize.
在服务器端，使用记录集的pagesize属*将搜索结果分割成区块，以限制在浏览器中同时显示的结果数。
Multiplying the two values — number of pages and the pagesize — gives the current size of the heap.
在以上代码示例中，如果pagenumber值为2,pagesize值为15，则变量prods将包含product表中第16行到30行的产品。
If MAP_FIXED is specified, addr must be a multiple of the pagesize.
