Hello,
First of all, thank you very much for Dynmap, which is still a must-have plugin!
I don't think it's a bug, but it's something that bothers me a bit: tiles/marker_{world}.json files are (re)written every 5 seconds, regardless of whether their content has changed.
My server is idle most of the time, and the only regular writing to disk are these files. So, is there any way to limit them? I also think it would be interesting to check whether there have been any changes before writing these files.
Thanks for reading, thanks in advance for your reply, and have a nice day!
