 ## Read Performance
 
-I did benchmarking mostly on my Macbook Pro laptop.  In general, the Julia implementation is somewhere between 10-100x faster than the Python counterpart.  Test results are documented in the `test/perf_results_<version>` folders.

 ### Numeric Columns Constructor
 
-In general, SASLib allocates native arrays when returning numerical column data.  However, you can provide a custom constructor so you would be able to either preallcoate the array or construct a different type of array.  The `number_array_fn` parameter is a Dict that maps  column symbols to the 
-custom constructors.  Similar to `string_array_fn`, this Dict may be 
-specified with a special symbol `:_all_` to indicate such constructor 
-be used for all numeric columns.
