The dependency service has been folded into the indexer
service which is running on
its own thread. What kind of delays are you seeing?
The dep/indexer service runs on
a low priority thread in the background - it should
not cause any noticeable delays. 
(Unless you are requesting a search/code complete
on an unindexed project. In this 
case you have to wait for the project to be indexed
before continuing.)

The indexer reacts to events and always tries to do
the minimal amount of work. For 
example, if you make changes to a file and save it,
the indexer will add only the changed
file to index [provided the index is up to date].
The only time the indexer will index an
entire project is: i) search request and index not
found or ii) index corrupted.

As the dep service is now part of the indexer (as
it is crucial to keeping the index up 
to date) it can't be turned off without disabling
indexing.
