I was just browsing kernel soucres (looking on how to improve sys V
messages to make them actually usable), and found this:
#define MSGMNI 128 /* <= 1K */ /* max # of msg queue identifiers */
#define MSGMAX 4056 /* <= 4056 */ /* max size of message
(bytes)*/
~~~~
why? Looks to me like this should be page-size - 40,
what do you think?
msg.h line 15/80 56%
Also, I get some rather strange behaviour with time command. (This is
about third time command I use: first showed wall time only, second
did not show pagefaults, this looks best)
jarka@Elf:~$ time netscape

~~~~~~~~~~~~~~~~~~
I wish this to be true... But it
is not. Why does linux measure
these values? Is it too much
overhead?
