Performance

1. I timed the downloading of some modules for about 10 stocks. But there isn't any difference in time between asynchronous=False, True, and True with different max_workers=8 or 16.
2. If I need to get multiple modules for thousands of stocks, what's the general recommendation for grouping the tickers for a batch request? I don't know how to deal with the max trial exceeded error.
3. For multiple modules, does it make much difference between requesting all reusing the same Ticker object, which is initiated with a list of multiple tickers (hundreds to 1000 in each batch out of 10,000 in total in my case), and requesting one module each time by repeating the loop over all the tickers?
