This paper addresses the issue of Moodle's performance within two different HTTP servers - Apache and Lighttpd. Under the 8-second rule, it is shown that in our test environment with PHP eAccelerator, for a Moodle's Quiz test the number of maximum concurrent users supported by an Apache server is about 60 to 70, whereas the number of maximum concurrent users supported by a Lighttpd server is about 130 to 140.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-07-09","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"11","bibliographicVolumeNumber":"2010-IOT-10"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-21T23:45:43.760834+00:00","created":"2025-01-18T23:29:11.393160+00:00","links":{},"id":69825}
