> [lots of syscall combining proposals snipped]
where's ingo? shouldn't he be jumping in here telling us syscall overhead is some impressively tiny number of cycles which is bare noise above the L1/L2 cache sloshing we'll see at scale? :) after all, we're talking about servers with 4k+ sockets, and alan cox tells us to budget about 23kb of memory per socket -- that's almost 100Mb of RAM... makes me wonder if combining syscalls is worth the complexity.
out of curiosity, has the fast syscall and fast gettimeofday stuff with the nifty kernel-supplied code page made it into the kernel/glibc/etc?
