Yes, the memory consumption is expected (because the file contains nearly 1
million lines and Calc does not support memory mapped files [YET!]).

However, the slowness of opening autofilter dropdown is easily fixable (read
complete section to the buffer and merge sort, which is O(n log n)). Current
method seems to be 2^(O(n)) :-\
