Description

Currently every cache-put require the following:
1) Find the page with enough space
2) Remove it from free-list
3) Update the page
4) Return back to appropriate free-list

When doing bulk data loading, we usually need to fill a lot of pages. To minimize free-list overhead we can do the following:
1) Allocate new page
2) Fill it with as much entries as possible
3) Add it to appropriate free-list

This could drastically improve free-list overhead and this improve loading performance.
