15. 15. Performance : case Brutex : 106 emails Customer Brutex: Koen Verwimp from Precisions Operations GO LOW LEVEL strategy Search on Lucene index Returns noderefs Metadata are retrieved directly from database (MySQL) Also works my MySQL slave replication (e.g. When you consult these data remotely: 100ms to retrieve meta data from local DB Avoid permission checks using folder based permission. By user profile, retrieve only documents from authorised folders Probably only high performance with low number of folders Note: Nr of documents: about 1 million. Average seek time : 500ms. Sorting on time (milliseconds) is the most time consuming steps, on time. Average seektime: few seconds. Satisfying performance on alfresco 3.1.x with 1 miljoen documentsDecember 17, 2010 15 2010 - Proprietary and Confidential Information of Xenit Solutions
16. 16. Performance : case Vera :webscripts What always applies: Measure before optimisation Rewrite the scripts in function of efficiency Caching (webscripts are HTTP cache enabled)! Memory versus CPU trade-off Explicit storage of document characteristics Denormalisation of properties Store parent properties in child for easy retrieval Webscript library optimization Resolve imports at package time instead of at runtime Alfresco specifics: Xpath-> Lucene Query Lucene: Filter using query clauses instead of filtering in script Java backed implementation Upgrade Alfresco regularly (ACL checking is faster!) Application level: Rethink your logic partition large result listsDecember 17, 2010 16 2010 - Proprietary and Confidential Information of Xenit Solutions
17. 17. Performance: CMIS versus Web services Loading documents: context :1000 folderscontaining 1 file. WS implementation : WRITE 3,5 docs/second Via CMIS (nov 2010) : WRITE only 1,5 docs/second Sames test : larger files: (2MB), difference smaller, but old interface remains faster. Deletion of files: same speed. Jonas Heylen: Voorlopig zou ik dus bij Vivium nog niet overschakelennaar CMIS. Zowel wegens de lagere performance als de beperkingen van deCMIS standaard (inheritance, aspecten, auditable properties) http://xenitsupport.jira.com/wiki/download/attachments/2293927/Move2alf+benchmarks.pdfDecember 17, 2010 17 2010 - Proprietary and Confidential Information of Xenit Solutions

Vital records absolutely essential to the organizations ability to carry out its business The documents become records when they are set aside, that is,captured into the ERMS.
