How to get a faster speed when using multi-threading in python

Question

Now i am studying how to fetch data from website as fast as possible. To get faster speed, im considering using multi-thread. Here is the code i used to test the difference

Answer 1

A DNS lookup takes time. There's nothing you can do about it. Large latencies are one reason to use multiple threads in the first place - multiple lookups ad site GET/POST can then happen in parallel.

Dump the sleep() - it's not helping.
