Hi
We did test against RT target but with about the same results.
We did however also test using NI's own Veristand client API, giving much faster writes, ~1ms. (not sure about the details of exactly what was verified except that the synchronous call only took the specified time)
https://buildmedia.readthedocs.org/media/pdf/niveristand-python/latest/niveristand-python.pdf
from niveristand.clientapi import ChannelReference
alias_ref = ChannelReference(variable)
print(alias_ref.value) # Read
alias_ref.value = new_value # Write
