Creating an issue with a long description causes 100% CPU utilization on Windows. The text I was adding to the description is attached as a file.

Which process eats up the CPU? Ruby or the DB?
#2 Updated by Erich Rockman over 1 year ago
Sorry. Ruby.exe.

Mmh, I don't have a windows machine so I can't try to reproduce it… Have you tried reproducing it on the demo redmine? If not, please do so.

I can confirm the issue. And it comes from Redcloth3 that takes minutes to format this 185kB text.
A solution would be to upgrade to Redcloth4 which is considerably faster for such long texts.

Thanks. I did a gem install RedCloth. It installed 4.2.3. How do I get redmine to see it. Seems to still be using v3. Thanks.

RedCloth 4 is not supported for the moment, see #6269 ; the patch provided there will just let you boot redmine with redcloth 4, but it's absolutely not functional (you'll have basic textile working, but not the additions from redmine itself, such as autolinking on ticket numbers, wiki pages, etc.)
