In my original post I can't analyse how many memory take hash tables...

And also it is interesting to know how much key-value pairs can hold hash
table.

================================================================

Also interesting thing about elisp that any related data stored in distinct
memory locations (ever any internal structs hold link to actual data, like
string for symbol name), non-together.

I think linked nature of elisp data structure cause very high rate of CPU
cache miss (but I don't actually run any AMD/Intel CPU profilers).
