This may be related to an attempt to check folder content after every single character is typed.

There are at least 2 points where directory content is being checked:
1) ServerWizardIterator.isValid(...)
2) AddServerLocationVisualPanel.AddServerLocationVisualPanel(...)

An attempt to read non existent remote content will cause remote read timeout and cause slowness in AWT EventQueue.

Fixing this would require all file system access code in wizard to be rewritten.

Report from old NetBeans version. Due to code changes since it was reported likely not reproducible now. Feel free to reopen if happens in 8.0.2 or 8.1.
