> Most of the time it did not matter that much to give the Server a GB more memory but recently we had some real issues with CloudFoundry. A long-standing difficulty with the Java Buildpack was working out how much memory to give it -- the Garden container engine is particularly ruthless to any process going above the allocated memory limit. I believe it got a lot of attention in v4 (edit: see [0] and [1]). My personal pet peeve is that the memory quota is identical for staging and runtime. Which means that memory-intensive staging operations force you to have wasteful runtime memory allocations. I mostly noticed this when using Rails apps that pull in Nokogiri -- it gets compiled during staging and often that causes a lot of memory usage.
