Today I want to talk about the patch I submitted toRuby in this ticket.It decreases “after boot” memoryusage of aRails application by 4% and speeds up require by about 35%. When I wa
I’ve been working onbuilding a compacting garbage collector inRuby for a while now, and one of the biggest hurdles for implementing a compacting GC is updating references. For example, if Object A points to Object B, but the compacting GC moves Object B, how do we make sure that Object A points to the new location? Solving this problem has been fairly straight forward for most objects.Ruby’s ga

Today we’ll use that information to write a program that will allow us to take aRuby heap dump and visualize the layout and fragmentation of that heap.Ruby Object Layout RecapJust as a recap,Ruby objects are fixed width. That is, everyRuby object is the same size: 40 bytes. Objects are not really allocated with m
