cache is implemented to improve I/O performance with data in disks. As buffer cache management, there are many mechanisms based on access pattern of block. On the other hand, we proposed I/O buffer cache mechanism based on the frequency of file usage (FFU). Our previous proposed mechanism calculates file importance from the information of system-call of the file operation. Then, it controls two level buffer cache based on the file importance. In this paper, we propose a setting method of opportunity of updating file importance on FFU. The proposed method focuses on whether the file state is access intensive or not. This paper also describes a setting method of parameters of the proposed method based on access information of a target system. Finally, this paper reports the evaluation results of the proposed method by using typical access pattern data and real access patterns.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1462","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1451","bibliographicIssueDates":{"bibliographicIssueDate":"2015-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"56"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":142354,"links":{}}
