AWS Lambda vCPU/memory ratio table
1
When Lambda maximum memory size was 3GB, we had official information that below 1.8GB it has 1 vCPU and above 1.8GB it has 2 vCPUs. So we were able to share some multi-threading optimization tips with the customers.
Now with support of up to 10GB of RAM and up to 6 vCPUs, do we have any official information on the number of vCPUs based on the memory size?

What's interesting is that for the
nodejs16.xinternally process detects different CPU configurations, we get:128-3008 MB - 2 Allocated cores 3009-5307 - 3 Allocated Cores
And rest of the numbers are as in the presentation
I wonder whether it's a quirk of Node.js CPU cores detection, or AWS does something different for Node.js specifically
