( #3333=superdoc: print w/replies, xml ) Need Help??

I can only wonder about the memory and CPU requirements...
Saving a bigger hash (ca. 515000 entries, where each key is about 7-10 chars long and each value is a Tree::Nary structure), results in a ca. 330MB file. Uncompressed that is.

Restoring it, takes an average of 3,8 times more memory than disk space => ca. 1,2GB!

Saving is weird, after all the 330MB have been saved, store takes another 2200 seconds of 100% CPU time on a P3 1,26GHz even after the complete file is already on disk.

Moreover, store seems to take when storing the same amount of memory as the data structure takes. in the aforementioned case over 2,1GB RAM are allocated! Gosh...
