I got a few questions;
1.) Is the 'priocntl' utility used instead of the 'nice' utility, or is it just
another priority tool?
I got the feeling it's the same as 'nice'....
2.) Is Dynamic System Domains the same as zones? The description of it feels
like it's _almost_ the same, but more hardware oriented division. (Link
for DSD information?)
3.) What's the actual difference between changing user priority and global
priority? What happends if I change both to maximum (say RT). Is the user
priority less worth the global? If I as root change the user priority, is there
any point in changing the global priority of the process/project?
4.) If I set a process/project to have a certain limit of memory allocation,
could this have positive effects on applications with memory leaks? If the
memory leaks cannot pass say 50Mb of memory, can these 50Mb be allocated with
non-usable memory (memory leaks) so the actual memory usage gets even worse for
the application?
And if I have have 4Gb of memory, and I set a limit of 3.5Gb to one application
that at a certain point only use 2Gb of the memory and another application uses
2Gb. Then suddenly the first application (the one with 3.5Gb limit) uses its
full limit (3.5Gb), what happends with the memory that the second application
had allocated (1.5Gb)? Does this memory get swapped to the HDD and the second
application only get access to the 500Mb memory thats left?
I hope you understand my questions even if they got a bit sloppy :)
Best Regards,
Nergal
