Why is iftop using so much memory? Are there any tools that are powerful, but do not use so much memory?

Question

pmap iftop_id

b7fce000      4K rw---  /lib/ld-2.5.so
bf9aa000     84K rw---    [ stack ]
 total   204940K

The memory of the server is only 1GB, but iftop takes 204MB. It is crazy that iftop uses so much memory - why? Are there any tools that are similarly powerful, but do not use so much memory?
