How is total record count used in paging?
Total Record Count the total number of records being paged through. While this variable isn t needed to determine what records to retrieve for a given page, it does dictate the paging interface. For example, if there are 81 products being paged through, the paging interface knows to display nine page numbers in the paging UI.
How does serving a full page from cache work?
With page caching in place, generated pages are saved/cached so that they don’t need to be regenerated each time when requested. Serving a full page from cache bypasses the server processing that goes into generating a page. This dramatically increases page load performance as well as pages-per-second throughput.
How does the page cache affect the CPU?
Sadly, in a regular file read the kernel must copy the contents of the page cache into a user buffer, which not only takes cpu time and hurts the cpu caches, but also wastes physical memory with duplicate data.
How does page view count work in WordPress?

What’s the maximum number of records that can be paged at a time?
For example, when paging through records 10 at a time, for the first page (whose page index is 0), the Start Row Index is 0 * 10 + 1, or 1; for the second page (whose page index is 1), the Start Row Index is 1 * 10 + 1, or 11. Maximum Rows the maximum number of records to display per page.
What happens when paging through large amounts of data?
When paging through data, the precise records displayed in a page depend upon the page of data being requested and the number of records displayed per page. For example, imagine that we wanted to page through the 81 products, displaying 10 products per page.
What’s the difference between default paging and maximum rows?
For example, if there are 81 products being paged through, the paging interface knows to display nine page numbers in the paging UI. With default paging, the Start Row Index is computed as the product of the page index and the page size plus one, whereas the Maximum Rows is simply the page size.
