Access to a functional global is your biggest source of jitter? But your "heavy load" access rates are in the order of ~5 client accesses per 50 msec? That doesn't actually sound very demanding. Is the code structured to cause client accesses to be syncronized rather than asynchronous? Are you sure the jitter is due to access and blocking effects rather than variable time spent inside the func global (or even elsewhere)?
Well, regardless, you may as well make the fairly simple switch to a standard global variable so you can compare.

CAUTION! New LabVIEW adopters -- it's too late for me, but you *can* save yourself. The new subscription policy for LabVIEW puts NI's hand in your wallet for the rest of your working life. Are you sure you're *that* dedicated to LabVIEW? (Summary of my reasons in this post, part of a voluminous thread of mostly complaints starting here).
