I suppose you're taking about the time needed to do a PROPFIND enumerating all
those resources.
Could you give more details about the request being made ?
As you know, the response to that request is XML, and is quite verbose
(especially a request for all properties). Therefore, it takes a long time to
generate, and then a long time to parse at the other end, since it's rather
likely that the client will use DOM to parse.
For one resource, the size of the XML generated for a PROPFIND with allprop is
about 3.2 K. So for 10 000 resources, that's 32 M ... Also, that figure is
bound to grow a bit when Delta V is added.
One thing which can be done to improve performance with large amount of
resources is add more memory and raise the cache limits (this is configurable
right now, but it could be a factor).
The solutions to this can only come from reducing the amount of XML generated.
You can :
- splitting resources across multiple collections
- avoid doing PROPFIND infinity requests (which is Slide are converted to Depth
3 - but apparently this is still too much, and this has to be made configurable)
- only do PROPFIND requests asking for specific properties (IE does this, and
this cuts th response size by 3-5)
