Actually, I found the issue. I will try to explain it as follows:
Assume that I have data that needs to be hashed by 4 different keys
(key1, key2, key3, key4). If there are situations where key3 and key4
are non unique and I make them the same value for every entry, when I
remove an entry from my table that has a lot of entries (ex. 10000), it
may take seconds to for the removal to take place.
Is there a way to improve on this? Something like be able to tell the
multiindex to not always hash a key if the value is not set (example, if
integer, value of -1 means not set)?
Thanks for any help.

That depends on your compiler and build system.
