Confused about MagmaCollections

[Thierry Lebourque]

Hi,

Diving into Magma, I have found some information that look, to me,
quite contradictory about MagmaCollections.

Here: http://wiki.squeak.org/squeak/2639 I understand that they are a
good choice for large collections of objects.

And here: http://wiki.squeak.org/squeak/2986 it is said that they
should not be used.

Well, I have a large collection of objects and MagmaCollections seemed
to meet my requirements in terms of accessing, but, according to the
wiki, not in terms of performances.

So my question is: are they usable or should I implement my own version ?

Regards,

Thierry
