I am working on a system designed to keep processes behaving properly and I need to test its memory usage kill switch. I am yet to find a way to quickly and efficiently use alot of system memory quickly with node.js. I have tried using arrays but it seems as if the garbage collector compresses them. Basically, I need to deliberately cause a fast memory leak.

EDIT: I need to reach around 4 gigabytes of used system memory by one process.

答案1:

If garbage collector is compressing your array, maybe you are pushing always the same value inside it.

you should try shomething like

var a = [] for (let i = 0; i < 9000000000; i++)
a.push(i)


You also should run your process with a flag to increase memory limit. Note that with a limit of 9Mld, your array will be bigger then 4GB and your process will exit with non zero status code.

node –max_old_space_size=4096 yourscript.js
