How long does it take to get an e-Visa?

e-Visas are issued by the foreign governmental agency and vary depending upon the country.  Some visas (such as Australian ETA's) can take as little as 30 minutes.  Others can take longer, more like 6-7 days to process.   That being said, electronic evisas are much faster than paper visas due to the lack of need to send documents, stand in line, and go through paperwork.  Its the most efficient way to obtain a visa for your trip.
