What you use to run as a webserver in background?

We have a project where we use Rails and Elm. Currently in CI, we are running webpack dev server as background webserver and puma ( from Rails) as background application server. Our integration tests passes locally always, but tests doesn’t run consistently in CI server. I set the default wait time to 70 seconds, still no luck. I took screenshots while ran the spec using SSH, it looks like the page is loading very slowly and going beyond the timeout I set. Any advise how can I fix this?

Please let me know if you want more information on this.

Still an issue?

I’d do standard debugging as if this was a local machine. How much RAM is being used? Processes runnings? Etc.

Also, which platform/build image is this running on?
