Do you really want to subject the web server to 150 simultaneous
requests? Some would consider that a denial-of-service attack.

When I scrape a site, and I have been doing that occasionally of late,
I put a 10-second sleep after each HTTP request. That makes my program
more considerate of other people's resources and a better web citizen.
It is also much easier to program.
