I've seen performance slow-downs when comparing Axis to Apache SOAP. I haven't taken the time to look into the Axis code but I will do so in the next few weeks and I'll post what I find here.
I put together a Performance Kit to let people test Web Services for scalability and performance. The kit uses my open-source TestMaker utility.
