Optimize Performance and Scalability with Parallelism and Concurrency
- Audience level:
March 8th 9 a.m. – 12:20 p.m.
From how the operating system handles your requests through design principles on how to use concurrency and parallelism to optimize your program's performance and scalability. We will cover processes, threads, generators, coroutines, non-blocking IO, and the gevent library.
How processes, threads, coroutines, and non-blocking IO work from the operating system through code implementation and design principles to optimize Python programs. The difference between parallelism and concurrency and when to use each.
The premise is that to make an informed decision you need to know what is happening under the hood. Once you understand the low level functionality, you can make the correct decision in the design phase.
The emphasis is on practical application to solve real world problems.
