bad performance

[chevibinder]

Hello,
I don't understand why it takes for me about 4 seconds to load a tif file.
I try load the same file in your demo: http://fcrohas.github.io/angular-canvas-viewer/
and there it takes 1 second. So, why the same example when it runs locally, has bad performance and loads the tif file so slow?
thanks,
Yocheved
