When running a source block and storing the result in a file the data will first be converted to a table in org-babel-result-cond and then converted back to text when org-babel-execute-src-block writes it to file. This is takes a very long time when the result is big and it is unnecessary. I have attached a patch that makes org-babel-result-cond return the scalar result when it knows the result will be turned into a file.
Regards,
Bjarte

Subject: [PATCH] ob-core: Do not return results on writing to file
When writing the result to file we do not need to first convert the
data to a table since it is just converted back when
org-babel-execute-src-block serializes the result to file.
* ob-core (org-babel-result-cond): Add "file" as a param that returns
a scalar result.
