Slow Channel Advisor imports after upgrading

[4444...@gmail.com]

We recently upgraded from 8.014 to 8.02 and ever since we have been having incredibly slow Channel Advisor imports.  These were working fine before the upgrade. An import used to just take 1-3 minutes and now can take upwards of 15 minutes. I'm assuming this has something to do with the implementation of MSXML 6.0 in version 8.019.

Is there anything we can do to speed this up or go back to MSXML 4.0?
