for the imagebars, make sure you only put the parts that will change on them, i see a lot of black on the image, remove all that, make it the smaller it can be, so it draws faster, but if its still slow, split it into more imagebars, also, make sure the image has no "transparency color" since that draws slower.
The way the display works is that it draws everything pixel by pixel, so the bigger the image, the slower it is, doesnt matter if everything is the same color.
Transparency mode for images is slower beacause it has to skip the draw of a pixel that contains a specific color, so thats an additional check. The display has just ~16mhz of speed.
For the numbers with the imagebar, i added a feature to the imagebar so its easier, you can now select to use a specific digit from the sensor as the value for the imagebar.
You will either need to make them "transparent" with the full set of bars the number has as black or create every set with the background that part of the number has.
For the mhz numbers i recommend just using a look-alike font with transparency, since its that small you shouldnt need that antialiasing and transparency should "work" -option "Transparent BG (Partial)-" and set the font background to black, this should create this sort of effect with time
