Demo to illustrate Ruby threads when calling external APIs. Ruby threads are governed by the Global Interpreter Lock( GIL), which ensures only Ruby operation is executed by the interpreter each time. More info on Ruby threads:
bundle install to install dependencies
start 2 separate server processes:
ruby api/server.rb -p 4567ruby api/server.rb -p 4568
execute client:
ruby client/app.rb
The code will execute 2 sets of tasks, each with and without threads. It then prints out the total time in seconds taken to complete each task.
