Version Used:
2.6.0-vs-for-mac-62303-01

3. Observe that 64MB are coming in from SQLitePCL.util.to_utf8

Expected Behavior:
http://source.roslyn.io/#Microsoft.CodeAnalysis.Workspaces.Desktop/Workspace/SQLite/Interop/SqlConnection.cs,210

Should be using cached values that can be passed to native. "main" and DataColumnName are both constants. DataTableName can also be cached per accessor kind

Probably a lower level layer should be used for better performance. Passing in strings will cause SQLitePCL.raw to create byte arrays from the strings every time.

Actual Behavior:
These strings are marshaled to byte arrays on every blob read.
