Example showing processing time difference for filtering numpy signals along different axes.
import numpy as np
from scipy import signal
fs = 30000 # Hz
n_chans = 100
sig_dur = 300.0 # seconds
lp_cutoff = 250 # Hz
lp_order = 8
sig_freq_low = 14 # Frequency of sine wave in signal
sig_amp_low = 10.0 # Amplitude of sine wave in signal
