I would suggest this is a question for the kernel people. I have a vague memory (pardon the pun) of there being some issue such that if you did have vast amounts of RAM, some data structure grew rather large and the kernel spent a disproprtionate amount of time servicing that. The fact that I've seen that, though, PROBABLY means that it was mentioned as part of a fix. In short, make sure your kernel is reasonably new (Something 4.0 or newer should be fine, maybe even 3.0 or newer). Oh, and from a hardware perspective, read the manual of your motherboard for how best to load the RAM; you will probably be instructed to load sticks of RAM in a balanced configuration in order to fully exploit parallel access by the memory controller. > > Thanks, > Dan > > > -- > To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org > with a subject of "unsubscribe".
