This slowdown is caused by the GenerateXML() method.  MLT can load very
complex XML files almost instantly.  If we can find a way to increase
the speed of our GenerateXML method, this will result in a dramatically
faster OpenShot. =)

Bug description:
When I have about 100 JPG photo files (about 10MP) Openshot get's REALLY slow. Up to 10 seconds just to change the position in the timeline (programme gets grayed out in this time). CPU: 100%, RAM: 33% - so RAM is not the problem. The CPU is a Dual Core 2GHz (Intel core 2 duo CPU T5870 @ 2GHz). Is that too slow??? I wonder because everything is fine with only a few files.

Thx,
k_s
