Apache compression feature to speed up Lucene retrieval of GS versions of some docs

Reported by: ak19 Owned by: nobody
Priority: moderate Milestone: Possible 2.88 Release
Component: Greenstone2&3 Severity: major
Keywords: Cc:


Lucene retrieval of Greenstone version of document slow in TestDocs?' 592Report.doc and one of the 2 xls files. But it retrieves the doc and xls versions fast, and deals fast with displaying the Greenstone versions of other doc and xls files in the collection.

Dr Bainbridge thinks this is because Lucene retrieves data from the index in a different manner to MG(PP): that it has to decompress it first. His idea is to let Apache do the decompression, by switching on the Apache compression feature when the user is using Lucene (or allowing the user to turn this on somewhere and letting them know of it). Putting decompression of Lucene-retrieved docs at Apache level may make things faster.
