IT systems, including banking systems, perform online and batch processing on a daily basis. To separate the impact of both processings, typical banking systems employ individual computers dedicated to each processing. However, with the improvement of computer performance, computer resources of each dedicated system are not fully utilized. Since the use of computer resources for online and batch processing is different in time, it is expected to improve the utilization of computer resources by executing both processings on the same computer. In this system, it is strongly demanded that the workload of both processings are distributed so that the workload of batch processing does not affect the response time of online processing. It is not enough only controlling to assign each workload to processor units of a computer using priority of online and batch processing, and it is also needed to distribute I/O requests to a disk. In this paper, we propose an effective method for maximizing disk I/O performance under composite workloads. Our basic idea depends on the fact that workloads of online and batch processing (1) have different peak times in a day, and (2) have different I/O patterns of disk access and lengths of data. We describe the I/O control mechanism in FreeBSD and the evaluation of it in this paper.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"286","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"275","bibliographicIssueDates":{"bibliographicIssueDate":"2020-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"61"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":203147,"updated":"2025-01-19T20:39:07.588885+00:00","links":{},"created":"2025-01-19T01:05:35.629861+00:00"}
