| | 19 | Indeed, VAL is the limit of user memory. Everything above that is kernel memory. Everything below it is user memory. So, if you need to run a lot of apps, you need to keep it higher, not lower. But if you need big JFS cache or use VPC (it, unlike VBox, allocates VM memory from kernel arena), you need increase kernel arena, i.e., lower VAL. So, you need some balabce between these. |
