It honestly really depends on Visa Office, complexity of application, country etc. Some people are seeing decision made in a matter of months, and others it will take longer, so it's hard to say. If you can find a thread dedicated to the specific VO your application will be processed at, they often have spreadsheets tracking progress of applications. For example we are Irish Outland applicants and are 5 months in still waiting (like many others, and others who have been waiting even longer) but a Cuban Outland app got request for Visa pickup in 3 months. It varies, no one will ever be able to say exactly how long it is.
