text: Thanks. I ultimately decided just to delete the whole area. As there was a bunch of none farmland stuff inside of it that can be mapped better and that seems to be the trend anyway. 
  
  I think your right about the other stuff. I haven't had any slow down problems with JOSM ever. It runs surprisingly well for being based on Java. I guess the sacrifice is that it has Java security issues (maybe not). iD Editor wasn't bad on performance when I first started using it a few years ago. It really tanked with the last update where they added QA stuff though. Now even with all that stuff off it takes like 1.5GB of memory in Chrome to do basic stuff and there is always short pauses between doing things. For some reason it only takes around 800mb in Firefox though. Which still isn't great, but 1.5GB is ridiculous. I don't know what the deal is. Hopefully it's just a memory leak bug that will be worked out in the next update. I seem to be the one to get them all for some reason. 
  
  Anyway, at least this is dealt with.
