Performance problems with large file lists

[DanielAW]

( Edited title. – Jan)

For better performance while loading folders with huge number of elements in it it would maybe faster when only the first 100 elements will be displayed.
The rest of the elements could be accessed by page turning: Lazy Loading

See: http://www.primefaces.org/showcase/ui/datatablePagination.jsf
(I know evil Java ;-)

Please just state the problem, we will decide on proper solutions and implementations. Pagination for example makes no sense for file lists, or any lists for that matter. It is highly intrusive and creates extra work for people. A better solution for this would be to handle this via virtual lists, for example like described in http://sergimansilla.com/blog/virtual-scrolling/
I edited the title accordingly.

And as always, we’re happy about pull requests. @DanielAW can you work on that? Also join us in #owncloud-dev on IRC.

@jancborchardt
I would try to imlement that. But it will take time for me to study the code. Im not totally familiar with PHP.
I would give me a maximum time limit of 1 month. Whould that be ok?

[jancborchardt]

@DanielAW sure that’s ok! We’re an open source project and I’m not your boss. :) Just make sure to join #owncloud-dev on IRC so we can help you with any questions. Also, this specific issue is probably better solved with JS/AJAX than with PHP. Anyway, if you look into it you’ll probably know better what works good. :)

cc @icewind1991 @butonic just for info.
