Hello,
Sorry but the forum doesn't allow to attach files. All tests done on the test servers return a good performance without issues.
Please open a support ticket with a script that illustrates your issue without doing external connections (such as databases or web services) and the dev team will run it on the test servers to check its performance. They need to run the script changing only the path to phpdocx and to the DOCX ouput; so it shouldn't include frameworks, CMS and other external codes.
We also recommend you to include in the support ticket the time taken to run the script (with and without WordFragments), so they can compare them with the test server output.
Regards.
