BAC0 Python fastPoll issue

Question

I'm trying to read an analog value from a Bacnet device every 100ms but the fastest i'm ables is every 1sec. Would anyone know why?

import BAC0
import json
import time
from datetime import datetime

bacnet = BAC0.lite(ip="192.168.1.8/24", port=47809)  
BAC0.tasks.Poll.DeviceFastPoll(bacnet,delay = 0.1)
data = {}


def main():
    while True:

        try:
            print(str(datetime.now()))
            print(bacnet.read('192.168.1.5 analogValue 101001 presentValue'))


            time.sleep(0.1)

        except KeyboardInterrupt:
            print ("Bye")
            sys.exit()
        
        

#RUN main
if __name__ == '__main__':
    main()

Result:
