4s in 327781: org.netbeans.modules.java.source.parsing.FolderArchive.getFiles() blocked in access to disk.

4.5s in #316932: too old report

3.6s in #292542: java.util.zip.ZipFile.getEntry[native]() - not much we can do about that unless we find out the native thread dump

3.7s in #281495: java.util.zip.ZipFile.open[native]() - again native code

I do not think there is anything we can do with the problem.
