The most prominent place I've noticed this is when SSH-ing at work, but I feel like I've observed this behaviour elsewhere too.

When I try to log into Linux servers from my Windows desktop at work, I've noticed that if I mis-type my password, it takes a good 5 seconds or so before I get "Access Denied" back. Then when I type my password correctly, the login (along with welcome messages etc) is virtually instant.

Is there any logical reason for this, or would it be down to some odd configuration that's specific to the machines here at work?


Question: How do I completely uninstall an app in OS X without the use of a dedicated app eg AppZapper?
Answer: There are several steps you may want to take:


remove any support files in /Library
remove any support files in ~/Library
remove any installed kernel extensions
remove any cache files left in /LibraryCaches
remove any cache files left in ~/LibraryCaches
Generically: remove any file created by the application at installation or during its run time.


To answer the question I think you want answered: there is no built-in facility to remove all traces of an app that you wish to uninstall (which is why programs like AppZapper exist at all).
