sizeof() not working correctly with Dataframes

[jdiaz97]

sizeof() returns the size of a variable in bytes. This doesn't work with dataframes as it will return very small amounts that don't represent the actual size.

I have very normal 13312×5 DataFrame and sizeof() returns 48 bytes.

sizeof returns the size of the object (and DataFrame itself is a small object, however, it can hold references to large objects).

You probably are looking for Base.summarysize which computes the amount of memory, in bytes, used by all unique objects reachable from the argument.
