Will running multiple pys in parallel with pycharm become slower?

Running multiple Python scripts in parallel in PyCharm may slow down because each script consumes independent CPU resources, memory, and process scheduling overhead. Speed ​​is affected by computer performance, script complexity, number of scripts, and resource competition. Optimization measures include using multiple threads instead of multiple processes, limiting the number of scripts running simultaneously, improving computer performance and closing unnecessary programs.

Will PyCharm become slower when running multiple Python scripts in parallel?

Answer: Yes, it may be slower.

Detailed explanation:

When you run multiple Python scripts in parallel in PyCharm, each script uses independent resources of the computer. This means:

• Increased CPU usage:Each script requires one or more CPU threads to run, and increasing the number of scripts will cause CPU usage to rise.
• Increased memory consumption: Each script will create its own variables and data structures in memory. The increased number of scripts will lead to increased memory consumption.
• Process scheduling overhead: The operating system needs to schedule processes between different scripts, which requires time and resources.

Influencing factors:

The speed of running multiple scripts in parallel in PyCharm is affected by the following factors:

• Computer Performance: Your computer's CPU speed, memory capacity, and storage speed will affect speed.
• Script complexity: The more complex the calculations and I/O operations involved in the script, the slower it will be.
• Number of scripts: The more scripts you run in parallel, the slower it will be.
• Resource Competition: If other programs are also running and consuming large amounts of resources, the speed may be further slowed down.

Optimization suggestions:

In order to reduce the speed impact when running multiple Python scripts in parallel in PyCharm, the following optimization measures can be taken:

• Use multiple threads instead of multiple processes: Multiple threads run within the same process, so process scheduling overhead can be reduced.
• Limit the number of scripts running simultaneously: Determine the optimal number of parallel scripts based on computer performance and script complexity.
• Improve computer performance: Upgrading your CPU, adding memory, or using a solid-state drive (SSD) can increase overall speed.
• Close other unnecessary programs: Release system resources to improve operating performance.
