Slow background indexing

Apache NetBeans version

Apache NetBeans 27

What happened

While working on PHP project the mouse cursor alternates between the timeout icon and the normal icon for a long time, rapidly switching between the two icons.

After investigation we noticed big difference in times of background scanning.

For example in Netbeans 26 message.log contains following messages:
INFO [org.netbeans.ui.indexing]: Indexing started, time from last indexing 143 888 ms.
INFO [org.netbeans.ui.indexing]: Indexing finished, indexing took 432 ms.
INFO [org.netbeans.ui.indexing]: Indexing started, time from last indexing 61 205 ms.
INFO [org.netbeans.ui.indexing]: Indexing finished, indexing took 379 ms.
INFO [org.netbeans.ui.indexing]: Indexing started, time from last indexing 29 079 ms.
INFO [org.netbeans.ui.indexing]: Indexing finished, indexing took 468 ms.

While for Netbeans 27 message log contain following:
INFO [org.netbeans.ui.indexing]: Indexing started, time from last indexing 27 846 ms.
INFO [org.netbeans.ui.indexing]: Indexing finished, indexing took 1 343 ms.
INFO [org.netbeans.ui.indexing]: Indexing started, time from last indexing 187 382 ms.
INFO [org.netbeans.ui.indexing]: Indexing finished, indexing took 7 073 ms.
INFO [org.netbeans.ui.indexing]: Indexing started, time from last indexing 184 393 ms.
INFO [org.netbeans.ui.indexing]: Indexing finished, indexing took 9 249 ms.

this is to be expected. Indexing is going to be slower over the network, benchmarks are also not easy to do given the unpredictability of fine grained remote IO.
