The behaviour I've observed is that if no swap priorities are specified, they'll be done sequentially, with the first listed swap fs being given a priority of -1, the second is assigned -2, etc. Previous suggestions I've seen were that you should manually override the priorities to make them equal, in which case the kernel will give each page to the swap fs that it expects to get the fastest response from. Other reading suggests that with equal priority, pages are assigned round-robin. What really happens and what's the best way to handle swap priorities when dealing with swap devices of comparable performance (e.g., swap partitions on two different hard drives)? -- Geek Code 3.1: GCS d- s+: a- C++ UL++$ P+>+++ L++>++++ E- W--(++) N+ o+ !K w---$ O M- !V PS+ PE Y+ PGP t 5++ X+ R++ tv- b++ DI++++ D G e* h+ r++ y+
