Description
Describe the bug
When comparing the performance between the modern diag manager and the legacy diag manager, you can see that the performance of the modern diag manager is consistently 4-7% slower than the legacy diag manager
To Reproduce
Compare performance between the modern and the legacy diag manager
One way to improve performance is to avoid x**power (where power is equal to 1)

Another way is to avoid having diag_send_complete loop through all the variable to check if it is time to do the buffer math/write output if send_data has not been called since the last time diag_send complete call.
Another way is to explore using do concurrent loops to parallelize the do loops when doing the math
Expected behavior
The performance should be similar or better
System Environment
This will happen in any system
