Yep. I think that if we could use the same conventions in both places, it would be nice. Not a requirement, just a nice-to-have... I realize that the styles don't currently match. Mike Rafael Vanoni wrote: Michael Pogue wrote: I was thinking mostly in terms of matching the existing n

Yipes! The 32-vs-64-bit thing bites us a lot when people are doing Linux-to-Solaris comparisons. If you just say "gcc" on Linux on a 64-bit CPU, you get a 64-bit binary. On Solaris, the default is 32-bit (even on a 64-bit CPU), unless you use -m64. This was done for maximum portability (32-b

IMHO, it depends a lot on exactly what the app is doing. I can think of a couple of possible reasons for the differences here: - the time taken by the memory allocator itself (depends on how many, and what sizes you're asking for), and - the exact placement of the memory can also (greatly) af

Andrei, That's percentage of what, exactly? For example, if one CPU is in a low power state (I know Solaris 10 doesn't do this now, but I'm thinking ahead to the future), then does the X% CPU cap represent the fraction relative to a all-CPUs-full-on 100%, or to the reduced-power-condition's
