Snapshot 1:
java.io.WinNTFileSystem.canonicalize0[native]()	50.303417	5 237 ms (50,3%)	5 237 ms
java.io.File.exists()	25.26316	2 630 ms (25,3%)	2 630 ms
java.io.File.isDirectory()	24.28	2 527 ms (24,3%)	2 527 ms

Snapshot 2:
java.io.WinNTFileSystem.canonicalize0[native]()	72.55958	7 247 ms (72,6%)	7 247 ms
java.io.File.isDirectory()	10.242512	1 023 ms (10,2%)	1 023 ms
java.io.File.exists()	9.900529	988 ms (9,9%)	988 ms

Snapshot 3:
java.io.WinNTFileSystem.canonicalize0[native]()	94.48297	10 987 ms (94,5%)	10 987 ms
java.io.File.exists()	4.33215	503 ms (4,3%)	503 ms
java.io.File.isDirectory()	1.1279899	131 ms (1,1%)	131 ms

So, it seems that the FS was busy, in all the cases. Unfortunately, likely nothing we can solve in NetBeans.

Thanks.

I will change it to use FileObjects, maybe it will help...
Comment 4 Tomas Mysik 2013-05-20 13:56:41 UTC 
Could be better now, I hope.

Using FileObjects instead of Files.
