Good for you, you even had a notoriously difficult visa office location, (almost 50% refusal rate, long processing times for Ghana), yet you got your wife PR in just 5 months. This goes to show, to anyone out there, that it doesn't matter how long a VO's processing time is, if you have a solid application with minimal red flags, you will get approved quickly.
In your case, you got yours fast because likely your relationship was solid and you had all required documents.
