I tried hash (where the members of a group are joined with ":"), and hash
of hash. It happended that hash of hash is slower than single hash.
Hash:
$groups{$g1} = "$member1:$member2";
Hash of hash
$groups{$g1}{$member1} = 1;
Method 1 is faster, even I need to do a split to get the members.

I am wondering if the performance (time efficiency) of hash of hash is bad.
I has this impression from the code I developed. Basically my structure
needs to hold the members of different groups. I have different choices:
hash of hash
$groups{$g1}{$member1} = 1;
but this one is really slow from what i see.
How have you seen this to be slow?
