It appears as if DCP-o-matic when analyzing the second file, is initially going through the first file (hence the negative progress), but creates a null ouput from it. When it reaches the second file, a real analysis starts. I assume this would also happen with the third, fourth, etc file. So, analysis is not actually 'slow', but delayed.

Yup, very easy to reproduce, e.g. with SINTEL. The negative percentage is calculated based on the runtime of the first file(s).

You can e.g. load Sintel - the analysis runs through normally. Load the same Sintel a second time - the analysis begins at -100%, crawls to 0%, then the actual analysis of the second source content is started from 0% to 100%.

If e.g. I load Sintel first, let it analyze, then load the shorter BigBuckBunny, the second analysis starts with -2580%, and it takes as long to crawl to zero as it takes to analyze the Sintel.

The second analysis is unusable, as all the null-values of the preceding files' analysis are contained in it.

Fixed for me, I can have multiple files loaded now and all are analyzed properly.
