Option to increase or remove heap memory limit

Open kzhsw opened this issue 1 year ago • 2 comments

Description

Make an option, in flags or command-line, to allow users to increase or remove heap memory limit, to use heap larger than 4GB in systems with much greater memory.

Who's implementing?

  • [ ] I'm willing to implement this feature myself

The problem

Currently chrome limits the heap memory (or the memory of a render process) to likely 4GB, but larger heap would be useful for debugging heap using the memory profiler, or running large, resource-consuming app on web. This is previously discussed on many forums, but now I can not find a thing that works without rebuilding the chromium itself.

Possible solutions

  • Make the flag --max-old-space-size and --max-semi-space-size work like in node.js
  • Make a flag to disable pointer compression (this could be a compile-time flag)
  • Get things upstreamed

Alternatives

Use Firefox which has larger limit on heap, and a slower js engine.

Haven't tested it, but does this work:

chrome --js-flags="--max_old_space_size=8192"

Haven't tested it, but does this work:

chrome --js-flags="--max_old_space_size=8192"

This could increase limit for ArrayBuffers, but not js objects, nor postMessage
