Drawbacks of Using Max Allocation Counts?

What drawbacks are there to always using the max allocation count for things like user limits and math blocks?

Hi @todd_mm,

I recommend only allocating the ones you plan to use.

Processing:

  • An enabled unconfigured Math block costs you a loop pass + pointer math + function call + switch/return. This is a very small non-zero time consumption every sample.
  • UserLimits shouldn’t process unless you call any of the UserLimit functions with that UserLimit #.

Memory (varies based on 32bit vs 64bit builds):

  • UserLimit: 448 bytes on 32-bit firmware, 608 bytes on 64-bit firmware.
  • MathBlock: 96 bytes on 32-bit firmware, 120 bytes on 64-bit firmware.

What evidence might I observe if I’m asking the RTA to do too much calculation?

Hi @todd_mm,

I’d recommend you check out

It isn’t perfect but can help give you an idea of what is going on.

An inability to keep a network operational is the surest evidence of overload.
