Abstract
Provided are a method and an apparatus for managing a page cache in a virtualization service and a method for managing a page cache in a virtualization service according to an exemplary embodiment of the present disclosure includes: comparing a weight value of a container and a weight variable of a page possessed by a process operated by the container in the virtualization service with each other, changing the weight variable of the page based on a comparison result, and managing pages of the page cache using the changed weight variable of the page.
Claims20
A method for managing a page cache in a virtualization service, which is performed by a page cache managing apparatus comprising the page cache storing pages, the method comprising:
- checking a weight value of a container in the virtualization service;
- comparing the weight value of the container with a weight variable of a page;
- changing the weight variable of the page based on a comparison result;
- and
- managing the pages of the page cache using the changed weight variable of the page,
- wherein the weight variable of the page is an I/O weight value set in the page and stored in a page structure of the page.
An apparatus for managing a page cache, the apparatus comprising:
- the page cache storing pages allocated by a processor operated by a container;
- a memory storing at least one command;
- and
- the processor connected to the page cache and the memory,
- wherein the processor is configured to:
- check a weight value of the container,
- execute the at least one command to compare the weight value of the container and a weight variable of a page with each other in a virtualization service,
- change the weight variable of the page based on a comparison result, and
- manage the pages of the page cache using the changed weight variable of the page,
- wherein the weight variable of the page is an I/O weight value set in the page and stored in a page structure of the page.
