How to convert wiki pages with base64 embedded images using UWC importer?

Question

It seems that UWC tool is choking when it has to convert wiki pages with base64 images.

I am trying to convert a wiki from twiki to Confluence and I came around this problem.

It seems that the size of the page is directly proportional with the slowdown and pages over 250kb seem to never end.

I had to increase the max memory to 2GB because the default 256KB was clearly not enough.

Hello team, it appears that the application does not cope well with such format as per https://jira.atlassian.com/browse/CONF-33189. Consider converting the image data to another format prior to the import task, since the issue does not appear to be with the UWC conversion task.

Hope it helps.
