Improve thinkorswim Performance
Jan 26, 2017
By default on Linux, the thinkorswim chart performance is absolutely abysmal. This is caused by Java 2D not being enabled. To enable it you must edit the shortcut for the application. This should drastically improve the performance. However, right click menus are still extremely slow but this might only be an issue with the amdgpu driver stack.
/bin/sh "<your thinkorswim path>/thinkorswim" -Dsun.java2d.opengl=true
On macOS this does not seem to do anything (Haswell integrated graphics).
