Evaluated just a few latest snapshots (these ones are more relevant):

snapshot-248084 - slow FS:
java.io.WinNTFileSystem.canonicalize0[native] ()	407 ms (18,5%)	407 ms (18,5%)
java.io.WinNTFileSystem.canonicalizeWithPrefix0[native] ()	100 ms (4,6%)	100 ms (4,6%)
java.io.Win32FileSystem.hashCode ()	39,0 ms (1,8%)	39,0 ms (1,8%)

snapshot-812865 - deep type hierarchy. I hope fixing issue #245279 could help here.

snapshot-819835 - slow FS:
java.io.WinNTFileSystem.getBooleanAttributes[native] ()	1 991 ms (52,2%)	1 991 ms (52,2%)

snapshot-820545 - CSS completion; slow FS:
java.io.UnixFileSystem.getBooleanAttributes0[native] ()	204 ms (12,8%)	204 ms (30,4%)
java.io.UnixFileSystem.getBooleanAttributes0[native] ()	60,2 ms (3,8%)	60,2 ms (9%)
java.io.UnixFileSystem.getBooleanAttributes0[native] ()	170 ms (10,7%)	170 ms (18,5%)
java.io.UnixFileSystem.getBooleanAttributes0[native] ()	296 ms (18,6%)	296 ms (32,2%)

snapshot-821711 - slow FS (plus Lookup?):
java.io.UnixFileSystem.canonicalize0[native] ()	308 ms (11,3%)	308 ms (12,8%)
java.io.UnixFileSystem.getBooleanAttributes0[native] ()	197 ms (7,3%)	197 ms (8,2%)
java.io.UnixFileSystem.getBooleanAttributes0[native] ()	78,1 ms (2,9%)	78,1 ms (3,2%)

snapshot-821712 - slow FS (plus Lookup?):
java.io.UnixFileSystem.canonicalize0[native] ()	127 ms (9,9%)	127 ms (9,9%)
java.io.FileInputStream.readBytes[native] ()	78,4 ms (6,1%)	78,4 ms (6,1%)


So, mostly slow FS issues we cannot do anything about, sorry. As I wrote, I hope that fix of the issue #245279 should help in most of the cases.

Thanks for reporting.
