I am writing a SageMath program that I want to run from within the editor (I use Atom editor, with a plugin that enables me to run sage). Whenever I run a script, it takes about 1.5 seconds, even if the script only writes "hello world". In contrast, when I run the same script using Python, it takes only 0.04 seconds.

is there a way to run SageMath scripts faster?

A possible reason could be that your plugin starts (a new session of) SageMath each time you run the script. And SageMath is very long to start (1 to 2 seconds on my laptop). Actually, this happens for instance if you invoke sage myscript.sage in a terminal: It takes ~1s + the time for the script to execute.

Yes, Sage loads a vast number of libraries each time it starts. Maybe forking processes or parallelism is the way to go?
