Those who have had this issue can you chime in?
Did you see higher LTFT in areas where you increased PFI or in areas where you increased DI?
The LTFT learnt at low loads should not affect OL. Usually it is the LTFT just below OL that gets carried into OL. So if the idle LTFT is off nothing to worry there, atleast not so much

I'm investigating this now. LTFT went up to +3.2 in the 0.2x-0.3x load area. Haven't
had the chance to perform a WOT run due to traffic, but OL at 1.0 load LTFT went into the opposite direction (-3.9).
I'm going to lower the port scaling a bit (to get it running
richer in CL) and try again.
