Very long document load times while running Siemens Teamcenter

I've asked this question here before, but I'm back again as it still persists. This has been an ongoing problem for a good number of years now. There was one time when an illustrator update came out and the issue seemed to be fixed, but that didn't last long. We use Illustrator, Teamcenter and NX in the creation of parts and service manuals for the machines we manufacture. The problem is that we need Teamcenter open to access the CAD models in NX, but when trying to open any document in Illustrator (with Teamcenter open), it takes forever. Seven minutes and thirty seconds roughly. However, as soon as Teamcenter is closed, the Illustrator document will open instantly. It doesn't matter if it's a new, blank document or an existing document. We just upgraded to the latest versions of both Teamcenter and NX, and our Illustrator is always up to date, yet the problem still happens.
