Loading and Changing Channel Delays

We have been with TABLO (Dual) for the past two months. We really like the various options in viewing our local channels. However, my biggest issues are: (1) Extraordinary amount of time it takes once you select the TABLE APP on the Firestick to the time you see the channel listing on the screen. I have timed this several times to be around one minute before we see the channel listing. (2) The length of time it takes to see the channel you select or change channels. Again, we are probably talking about 30-40 seconds before the picture appears. I have heard before the delays are caused by the data conversion from the OTA to the TABLO box and then to the TV. Is there anything that can be done to speed up this process?
