Some excerpts from the FAQ:
How long do you keep articles unread? Unread articles are kept forever. Although there is a limit of 500 total (both read and unread) articles per feed. How often feeds are updated? Refresh rate depends on the time of the last article in feed: few hours ago—each 15–45 minutes, less than a week—each 1–2 hours, less than a month—each 2–3 hours and 3+ hours for others. Feeds that support WebSub are updated in realtime. Do you support password protected feeds? Yes, feeds with HTTP basic access authentication are supported. How many feeds I can subscribe to? You can subscribe or import up to 3000 feeds.
So, let's pursue this: http://lists.gnu.org/archive/html/coreutils/2012-11/msg00079...
In my hands, `top` shows resident memory increasing steadily too....
It is perhaps more instructive to compare output from, for example
seq 1 1000000 | valgrind --time-unit=B --pages-as-heap=yes --trace-children=yes --tool=massif --massif-out-file=massif.dimsum.100000.out.%p dimsum -n 1
with
seq 1 1000000 | valgrind --time-unit=B --pages-as-heap=yes --trace-children=yes --tool=massif --massif-out-file=massif.shuf.100000.out.%p shuf -n 1
in my hands, shuf is faster and uses less memory for this task.
How about you?
