Garbage collecting becomes the critical part of Java virtual machine. It is significant to improve garbage collecting for total speedup. In this paper, we present three strategies for garbage collection (Allocation History GC, Hasty compaction, Segregated memory management). We have designed and implemented the strategies on JDK1.2beta3. The segregated memory management, which is a kind of GC without heap compaction, appears the best strategy among them. It can reduce 48.0% of total execution time and 67.2% of the cost of garbage collecting for the javac benchmark.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"30","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"23","bibliographicIssueDates":{"bibliographicIssueDate":"1998-05-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"33(1998-OS-078)","bibliographicVolumeNumber":"1998"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
