with "serverless" applications you can read the whole app into memory and run it and then clear it for the next app, which i'm sure speeds things up.

That's not how it works; programs are kept "warm" for some time after each requests, or indefinitely (e.g. in App Engine you can choose dynamic or resident instances).

Just chiming in to say this is also true for Lambda and Azure Functions.

What Id really like is for them to scale up to full fledged VMs once some usage or performance threshold was hit.
