That's only 2.4 seconds per stock. Depending on how much data each stock
provides, that doesn't sound like much time to me.
(1) How much data is downloaded? Perhaps you are downloading as fast
as your internet conection will allow.
(2) How long does it take to download outside of market hours? Perhaps
the supplier throttles the speed that you can download during market
hours, or perhaps they're just overloaded with requests and can't supply
information any faster.

Why do you think that downloading 10*100 stocks will take less time
than downloading 1000 stocks? Either way, you still have to download the
same amount of information.

Absolutely not. You shouldn't have the portfolio inside the script. You
should have one script, and ten portfolios. Then you give the name of
the portfolio as an argument to the script:
myscript.py portfolio1
myscript.py portfolio2
myscript.py portfolio3
...
myscript.py portfolio10
or possibly:
myscript.py portfolio1 portfolio2 portfolio3 ... portfolio10

One related question per email please. It makes it easier to follow the
conversations if you put unrelated questions in different emails.
