Andrew,
There is a limit to how much memory you can allocate in the kernel
space, if I remember correctly. On top of this, kernel memory is wired,
so allocating large chunks has a very negative affect on system
FWIW, a large percentage of the memory in the system is being wired for OS-Bypass networking via IOMemoryDescriptors which describe userspace addresses. Is there a restriction on the amount of wired memory in the system, such that if you have a lot of user memory wired, kernel memory allocations will fail?
performance. I forget specifcally how to set the limit for kernel
allocations unfortunately.
That would be handy information. Thanks, Drew _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list. They will be ignored.
