Using code below, I got ratios around 2.5-2.7.
Not so bad if carefully used.

I wonder how this figure would change in
upcoming releases. The reason I asked
the question, was to have some discussion
about the ingredients of it.

In short: Should we invest on it?

Regards,
Imran

now = datetime.now
async def main():

t1 = now()
for i in range(300):
foo1()
tot1 = now() - t1

t1 = now()
for i in range(300):
await foo2()
tot2 = now() - t1

print(tot2/tot1)

get_event_loop().run_until_complete(main())
