More efficient way to get bounding box of a bunch of SID images

I have a bunch of images in MrSID format (150 or more) with sizes from 3Mb to 10Mb each, and I need to get the bounding box that contains them all.

What is the fastest way of doing it?

My approach is as shown in the picture. It takes 1 minute for 3 .sid files (6Mb each). If reading a single SID file is slow, let alone 150. There must be some better way of doing this. Any idea?

Is there significant difference on processing time between the workspace containing a BoundingBoxAccumulator and the workspace just reading the source images without creating bounding box?

Besides, looks like you have run the workspace with Feature Caching. Feature Caching is convenient to debug, but it takes a long time to process since it cashes every feature on the workflow. I expect that the process would be much faster if you uncheck the Feature Caching option.

 

Anyway, I don't think the BoundingBoxAccummulator would be a major issue on the performance .
