I turned off postgres on the box, and at that moment all the used swap memory and about 500MB from active memory was cleared. Which raises a question: why is HAMMER using so much memory, causing applications like postgres to use swap (and thus run slow). The box has over 3GB of usable RAM, this should be well enough. I suppose HAMMER is caching the postgresql ondisk data? Should it cache it? FBSD+UFS2 with the same postgres dataset uses way less memory. My other box which runs DF with HAMMER has pretty normal memory usage but it doesnt run any database software. Petr
