The proposed method statically rewrites I/O instructions in device drivers of guest operating systems in order to execute multiple I/O instructions together. This reduces the number of switches between a guest operating system and a host operating system, and improves I/O performance. The proposed method has been implemented in the virtual machine monitor KVM of Linux. By applying the proposed method to a network device driver, network throughputs were sped up by up to 5.5 times in Linux and 4.9 times in FreeBSD.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2009-ARC-183"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":62053,"links":{}}
