4 years ago We have looked at this before but unfortunately there may not be much we can do. We import NumPy always, and Pandas if it is available. On my machine those alone account for the large majority of time:
In [1]: %timeit !python -c 'from bokeh.plotting import figure'
533 ms ± 5.29 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
In [2]: %timeit !python -c 'import pandas'
295 ms ± 2.78 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
In [3]: %timeit !python -c 'import numpy'
140 ms ± 3.78 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)There is nothing we can do about that overhead on our end.
That said Python 3.7 has a new import profiling mode. Quickly, without yet looking at them in any detail, here are the results that might point to some tweaks that can be made:

2.0.23.8.2Description of expected behavior and the observed behavior
