> hello,

Thank you for your interest.

> I am the owner of open source project,fastupload. It's more faster 5.x than apache commons
file upload in test. also, I test the form-based file uploading implementation of Servlet
3.0 API in Tomcat 7,  for example, HttpServletRequest.getParts(). it's slower than apache
common file upload.

HttpServletRequest.getParts() is just a wrapper around code copied
from Apache Commons Fileupload.  I would not expect it to be
noticeably slower.

> Now, I want to refactor the part code of form-based file uploading of Tomcat server implement.
to improve the performance for it.   sounds good?

If a problem is with the code from Apache Commons Fileupload project,
then I think it would be better to apply the changes to that project first.

After that the changes can be ported to Tomcat.

person I need to contact?

Contributions are normally discussed on the dev mailing list
and are submitted as patches via Bugzilla (for Tomcat) or JIRA (for
Apache Commons). They are covered by clause 5 of the Apache License,
