------------------------------------------------------------------

On my laptop, which is very fast, and has 64G RAM, compiling the p8 schema takes about 15 seconds. 

We shouldn't assume that is acceptable for our users who may not have access to quite as fast machines. 

The saved parser is only 667KBytes. The combined VMF schema that OKilo was dealing with compiled into 45Mbytes of binary. 

Startup time to parse a single p8 data file from the daffodil command line using the pre-compiled p8 schema just crated is 2.45 seconds. This is ok on my machine, but might not be on most users systems.

>             Project: Daffodil
>          Issue Type: Bug
>          Components: General
>    Affects Versions: 3.2.1
>            Reporter: Mike Beckerle
>            Priority: Major
>
> For large DFDL Schemas (e.g., combined schema using 3 different revisions of VMF together) compilation times are now exessive (many minutes), and even loading the binary compiled parser (45MBytes in size) takes like what seems to be a minute.
