I'm running 64bit Ubuntu and when I start pan, the memory usage
increases regularly until it hits up to 98% if physical memory and about
50% of swap; all up about 6GB.
Is there a way of reducing/controlling this
Text groups or binaries? Do you have groups with over a million posts
(including parts of posts which pan counts as one)? Especially Giganews is
known to be problematic, due to their long retention.
Once you get up over a million posts, scaling /does/ become an issue, tho
pan handles it better than it used to (the scaling limit used to be 100k
posts, but the rewrite with 0.90+ helped by using opportunistic string
combining in many places, including the count-as-one-post thing mentioned
above for subject strings, and in author strings, which tend to be
massively duplicated as well). Now, pan handles a million posts
/reasonably/ well, but has been observed to start having problems between
two and ten million (tho I've seen reports of 16 million plus working, if
you're patient and have the memory), depending on memory, number of
groups, number of servers and whether they carry the same groups, etc.
