Since releasing 0.6.5, I've discovered that the disk-based caching of review files is very slow for review projects with a reasonable number of files being reviewed. This shows as very slow loading of the file review pages.
Until I work out how to resolve this and get a fix out, the workaround (if you're finding this an issue) is to set:
jcr.reviewfile-cache.enable = False
in the 'app:main' section of the config file. The effect of this will be that page rendering will be a little slower for small projects, and much faster for large projects.
