x1 response time is horrible

The response time on my X1 Box is horrible.  And that's an understatement.  I thought my old X1 box was going bad, but I just had a new one installed commensurate with my new smart t.v. and this one is no better and sometimes worse.  Going from cable to Netflix, Paramount Plus, Prime, takes as long as a minute to load the home screen.  Disney+ takes almost two minutes, and it's a crapshoot if HBO Max comes up at all.  I had a technician come out and replaced my previous box.  The new one is different,  The old one had a digital clock/dashboard, this one does not.  If anyone has any suggestions as to how to fix, I would appreciate it.  If this cannot be fixed and it's something that I would have to deal with, I would appreciate that feedback as well so I can decide whether or not to live with it.
