[eclipse-clp-users] dictionary hash collisions

Hi all,

I have a rather large program with a lot of predicates and other symbols which 
fill the dictionary:

dictionary_entries:     20666
dict_hash_usage:        6816 / 8192
dict_hash_collisions:   7917 / 6816

I worry about the last line and the negative performance impact these 
collisions may have. What happens if there are a lot of hash collisions in 
the dictionary? Can this have a negative influence on the performance of a 
program?

Regards,
Stephan
