Dear perl users, I read a large file into a hash table. This hash table is used only once in the subroutine. I am very concern the memory usage, So I plan to realse the memory after used the hash table. The way I used is: my %hash = (); #read the large file into the hash table ... #release memory %hash = (); Do you think this way will really release memory usage? By the way, I found the hash table use much more memory than the array. I think hash table and array use different data structrue. it need much more memory to matain the hash tabe structure. I hope what I find is useful. Thanks Org
