12389	Poor performance when panning	ToeBee	nokutu	"This may just be #11929 not really being fixed but I suspect the root problem may be something else. I did see the .equals method being executed a lot but I think something is causing the draw method to be called an excessive number of times so I think the equals method being called a lot is just a side effect. I added a counter in the draw method to see how often it was getting called and every time the map view changes, it increments by about 12,000 in my case. At an execution time of 25 microseconds each time draw is called, that results in 300ms spent in the draw method. Add in some additional time in whatever calls draw and you're looking at a 500+ millisecond pause every time you pan.

An easy place to test this is highway 96 in Kansas. Someone uploaded about 10 sequences between Hutchinson and Wichita so there are a lot of pictures to load:
