After 905.701 upgrade - Excel and DWF files slow to open?

We did our upgrade to 905.701 last weekend.
Now this week most users are complaining that Excel spreadsheets are delaying opening, up to a minute. DWF files also delaying to open.
These are local and network files that are delaying.
We've tested everything I know of on this end including uninstalling Crystal runtime and the Epicor Client and the delays are still there.
I'm saying coincidence??
Anyone else have a similar experience?

Thanks in advance!
