And this cache is zfs's "ARC cache"? If yes: Doesn't the ARC cache allocate all its data from the kernel's heap? And since the kernel's heap is limited to 512 mbytes on 32-bit machines and maybe 50% of the heap could be allocated by the ARC cache - the rest is typically in use by other kernel code - this would result in an upper limit of ~ 256 mbytes of ARC cached data on any 32-bit machine (even when the 32-bit machine has 4 GB of physical memory installed)?
