This is the largest map I have ever worked on. I started in 2009, but I had to stop soon after I reached a few thousand labels. My Laptop wasn't ready to handle it and even my next PC with 16 GB RAM couldn't do the job properly. I did some merging to be able to work on different parts and put it together from time to time, but overall it wasn't really satisfying. Now, with 32 GB RAM, everything works just fine and I'm so happy that I could finally finish the map.
