Hi, ochrons,
This is just great,

Do you have any further bits of knowledge into why the FlatFileSystem approach is quicker than the current compiler code? On a machine, with additional Slam, all document framework gets to ought to be stored at any rate so memory planning versus perusing a zip file is essentially something very similar (aside from some trash created). Is it simply that typical container documents are normally gravely packed and smart is quicker decompressing the information?
