Dev environment slow to update Javascript files

[misaugstad]

With our new Docker dev environment (PR #1364), @aileenzeng reported some issues with the speed Grunt when it is run. She said that it used to take her <15 seconds to run Grunt with the old dev environment, but that it takes 45-60 seconds with the new Docker dev environment. This is a significant delay b/w making changes to Javascript code and seeing the updates on our local machines.

Hopefully @athersharif has some ideas for how to improve on that!

I will also switch over to the Docker dev environment and post about whether I am having the same issues or not.

#1364 (comment) for reference on what the underlying issue is. will push a pr soon to fix but would need volunteers using linux, mac, and windows to test this and double check :) @misaugstad thoughts on who would wanna volunteer? :)

@aileenzeng @andrew4699 or anyone else using Docker, is this still a problem? How quickly does grunt work when editing Javascript files?

[andrew4699]

It's pretty fast. Grunt takes about 5 seconds to run.

I’m not using Docker for my dev environment, but I can test this out later if needed!

[misaugstad]

Ahh no worries, just wanted to hear about any recent usage just in case, but no need to test again.

Copying over a comment on the PR from @mcdoerr

I was running into (15sec - more than a minute) load times with the occasional extremely long load time of about 3 min. I fixed this issue by allocated more CPUs and memory to the docker container, through docker desktop.

The changes for the docker container were 1 CPU -> 4 CPUs and 2GB memory -> 4 GB memory, though I suspect the CPU is what made the difference, not the memory.

Load times are now under 10 secs.

Running on macos big sur 11.2.1, docker version 20.10.2

Closing this now, since this seems pretty well resolves 🤩
