How to lower memory usage during build time?

[daydream05]

I have a website with less than 100 pages and uses Contentful for data sourcing.

But apparently the build time is already bigger than 1 gig which is the maximum for Gatsby Cloud’s free tier.

A lot of people got hit by build failures on Gatsby Cloud because of this unannounced cap. I don’t mind upgrading but I’m wondering if there’s a way we can we lower the memory usage or if there’s a way to track it.
