I have found that using timeout with a python queue.Queue() results in an average delay of  14.5ms in Windows over Ubuntu in python 3.6.5/3.7, I subtracted the 1 ms timeout.

I have also tried datetime.datetime.now() to measure the time, with similar results. 

Does that make sense?


import queue
import time

max=0
min=10000
num = 10000
sum = 0
for x in range(10000):
    q = queue.Queue()
    start = time.perf_counter()
    try:
        msg = q.get(block=True, timeout=.001)
    except:
        end = time.perf_counter()

    chng = end-start -.001

    if chng > max:
        max = chng
    if chng < min:
        min = chng
    sum = sum + chng

print(f"Avg: {sum/num}")
print(f"Min: {min}")
print(f"Max: {max}")

Results:
