How to decrease gatsby build time?

[snussik]

In general, its obvious that more memory and cpu you have on instance, the quicker builds you get. But I made tests on my quite big data source: 5000 rows in a plain Postgres table on different aws instances and saw no performance increase:

• m5.xlarge (vCPU/Memory): 4/16: 27m 27s
• c4.2xlarge (vCPU/Memory): 8/15: 23m 6s
• c4.4xlarge (vCPU/Memory): 16/30: 19m 5s

I run build process with NODE_OPTIONS=--max-old-space-size=32000 gatsby build --verbose

I realise that its not a linear dependency I doubling cpu cores won't give me x2 boost. But Its a strange situation and I think that its a bottleneck somewhere in gatsbyjs core.

ps. memory usage doesn't exceeds 8GB

So you're looking for decreasing in build time and not increasing, right?

Sure, edited ) As on my production data source with 120k records 16cpu/32gb it builds 10 hours.

Hi. Are you able to share your repo, or at least the build log output? 5000 pages is not particularly large, so the bottleneck might be something simple.
