Timothy's refinement of Anne's idea will work for me:
import timeit print '%.2fms/push' % (1000 * timeit.Timer( ... "a[...,:-1] = a[...,1:]", ... "from numpy import empty; a = empty((5000,20,1000))" ... ).timeit(number=10)/10)
537.86ms/push I still find the ring buffer solution appealing, but I did not see a way to stack two arrays together without creating copies. Am I missing a bit of numpy cleverness? Thank you everyone for your help, Alex
