18871	Performance issues after updating	ukash63@…	team	"==== Description
After upgrading JOSM from version 15806 to 15937 there is noticeable performance loss when moving nodes, ways or sometimes when adding tags. I noticed higher cpu usage. Downgrading to previous version (15806) fixes problem.
I have tested it on two different computers (with the same operating system).
