What implementation language do you use ? (C++, Java, ...)
What's the 'compiler output' ? (executable binary,  bytecode,  ...)

How is the hash table implemented right now ?

Is it implemented all by yourself, ...
e.g: What 'type' is the hash-key of ?  (string, object identifier, ...)
      Where is the 'data content' of the object instance stored in ?
(statically/dynamically allocated memory)

.... or is there some element / interface / library of your implementation
language you can use ?

What do you mean with  'better',
or, at least, where are your preferences  ?

Data Reliability ?
Performance ?
Memory usage ?
Flexibility in internal data structure ?

A lot of questions, I know.
But 'better' depends on them.

Kind regards,
Chris
