Tom Lane c22dea8900 Improve memory management code to avoid inefficient behavior when a context ... has a small maxBlockSize: the maximum request size that we will treat as a "chunk" needs to be limited to fit in maxBlockSize. Otherwise we will round up the request size to the next power of 2, wasting space, which is a bit pointless if we aren't going to make the blocks big enough to fit additional stuff in them. The example motivating this is local buffer management, which makes repeated allocations of 8K (one BLCKSZ buffer) in TopMemoryContext, which has maxBlockSize = 8K because for the most part allocations there are small. This leads to each local buffer actually eating 16K of space, which adds up when there are thousands of them. I intend to change localbuf.c to aggregate its requests, which will prevent this particular misbehavior, but it seems likely that similar scenarios could arise elsewhere, so fixing the core problem seems wise as well.		2006-12-27 22:30:48 +00:00
