Yes, I saw that code, but it only set a single variable and appeared to only be associated with a single instrument. If you have 100+ instruments, that would be 100+ separate updates. You know your code better than I and may be simplifying things for us, but I've seen cases sounding very much like yours where bindings is not the right solution. From how I read this, you are tightly coupling your view to your model. Consider decoupling your view-updating code like I suggested and you should see a significant change without a hack.

The timer fires every second and causes the whole 100+ fields to be updated. This, however, does not prevent KVO to operate for each setter being called.

Data format varies based on the data being displayed (I use the formatters to display the correct physical unit for each measurement).
