Potlatch 2 is becoming a major problem—I made my first edits yesterday successfully, but after an hour or so, and continuing today, Potlatch is virtually unusable due to the bandwidth limit. I’m getting errors after making only 2-3 changes in an area of approximately 30 NYC blocks. Being the type of person who makes corrections over a large area rather than mapping from scratch a small area, this will be very challenging. Merkaartor can’t download the data either, and Potlatch 1, while functional, seems to be very hard to use. (how to delete a way?)
I think it might be very useful if P2 had some form of “delayed load” feature. If one could disable loading data temporarily, one could pan based on background tiles alone. This way one would not loose the changeset while not overloading the api.
I have had similar issues, when trying to go on an OSM-I or keepright bug hunting session in an area. One quickly hits the API limit and keep switching between view and edit taps is a little tedious.
If you right click in the Map while editing and click the “Settings” option, a small panel will open. One of the sub-panels is for setting the local storage allowed. I found recently that my default setting was 100 Kb and I’ve increased this to 10 Mb. I’m not sure if it has impacted performance, but you might try this in your case as it sounds like a memory-related problem you’re having.
