I'm not convinced we want the part of your patch which modifies the caching
logic of checkCache. It'll speed up a "listing everything" case indeed, but
it's likely to slow down the "listing by predicate" case which is way more
We had to introduce a similar caching strategy in the HAL backend previously
exactly because of this. Now, the way we *fill* the cache in UDisksDevice is
far too slow, but it's a temporary measure done because of an issue with QDBus
@Lukas: This issue really need to be investigated ASAP. We have to place this
GetAll call. The way it's done currently through the metaobject kills the
performances as this one uses only Get calls (I checked QDBus code) so it
generates lots of round-trips on the bus.
