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.x internally 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
