You can get the initial startup time down by AOT compiling. I also believe that Lambda will re-use the same runtime and lambda function instance until a certain period of inactivity.
For example, in the example below I invoke the function (AOT compiled this time) three times. First invocation takes ~7s, the two following ~1.5ms.
