Hi I searched the group for 'measuring memory usage' with no hits.
I am trying to determine how much memory my cached data is using. I have some large data blocks that are not caching properly[1]. I am assuming that is due to there being a smaller numer of large 'buckets' and I have used all mine up? I am in the process of breaking it down into more sensible chunks (e.g. one data hash has 1000s of subkeys that I can make into cache hits on their own). However I would ideally like to know how much memory I am using as I have absolutely no idea if I am near the saturation point of allocated memory or not. I feel a bit dumb as this seems to be either a) common problem and I am incapable of finding the answer myself or b) a stupid problem that nobody ever thought someone would get into. This is running on a linux box (a few flavours), using perl. [1] By this I mean that sometimes, after a period of time, the cache retrieval is empty (before expiry). Basically I don't know why. Could it be some other application eating the memory? Or is it other large keys being set, pushing it out? Or am I using up all the allocated memory?
