Explanation of GC behaviour
by Norbert Hartl 05 Jul '19

05 Jul '19

I’m trying to understand better how the GC works because I cannot derive that from the parameters in the VirtualMachine object in the pharo image. Can someone sketch the position lifecycle of an object or point me to a document where this is described? Maybe the following questions help in helping. - object allocation happens in eden space? - after a few cycles eden space objects are considered survivor. Which is the process for a cycle? incremental GC run? - survivors are moved to youngSpace? After how many cycles? - after a few more cycles an object is moved to old space? - the term tenuring describes the process of moving object from young space to old space or also from eden to young space? - when is a full GC triggered? - a full GC is the only process that removes objects from old space? - the size of eden space and young space are fixed or relative to heap size? - how big is the initial size of old space when the vm is started? - if the heap size is not restricted is it likely a full GC happens or does the heap grow indefinite? - what does the VirtualMachine>>#tenureCount mean? Is the tenuring runs or tenured objects? Before the list gets to long I stop here. Your answers might remove many of them already. thanks in advance, Norbert
