I said I was done, but I lied. I suck. IMO we need:
-vcache/inode separation, with inodes containing vcache hints that must be
verified on binding. the current situation where we have effectively our
own inode pool needs to die
-SMP-fast instead of mere SMP-safe
We *may* need:
-rx performance enhancements. nobody has yet quantified that it's really
rx and not a client or server issue, but i suspect what Hartmut has
pointed at indicates a direction: SMP linux kernel on UP machine performs
better.
We should also have:
-stop using pioctl for things which should be a sysctl
-other than "group encoding" for PAGs, but I think Linux Security Module
has to survive for this to happen, and last week that wasn't clear.
