The delays after file saving for me are about
30-40c. During this time main thread is busy, so I cannot do any UI
action. If I interrupt main thread, I see that it is running on
IndexManajer.performConcurrentJob. It means that during sleeps all threads have
a chance to run, but the main one.
If I add the following line :
System.out.println(resource.getLocation().toString()
to AddCompilationUnitToIndex.indexDocument, it prints after file saving the names of all workspace
files. Does it correct detection that it re-index all workspace once again?
Could it be a result of bug # 44305?
About switcher. Of cource there can be different
opinions about this issue. I think that these two (dependency checking and
indexing) are different services, though tightly connected. BTW, I
guess that switching on/off for indexer has also disappeared..

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.
